Knife chat: Leatherman keychain tools- making a choice for hiking

Making a final choice…

Though fiddly, and occasional needing an extra bite, the small bottle opener on the Squirt S4 will do just that

Though fiddly, and occasionally needing an extra bite, the small bottle opener on the Squirt S4 will do just that

Over the past few days I have been looking at the various little multi-tools that Leatherman have released over the years with the aim of seeing which is most suited for taking hiking.

As you can see from the tool table below, a wide variety of capability is provided by these little multi-tools. However for Three Points of the Compass, the E4 is just about useless on trail whereas almost any of the remaining eight, shown above, would be a great partner.

The lack of any scissors on the Squirt P4 also precludes this tool from any gear list I would compile. I can see how many hikers would pick the Micra or Style PS from this line up. Certainly the latter accompanies me as part of my Urban EDC to work each day. Inclusion of a pair of pliers would be a nice feature on trail however I prefer a full size pair of scissors over pliers which narrows my choice to just three: the Micra, Squirt S4 and Style CS. All three have a similar blade. So it comes down to what other features are included and all three in my shortlist have similar extra tools. While I have a pair of tweezers in my First Aid Kit, I still prefer removable tweezers over those fixed to a multi-tool such as the Micra and those in the Squirt S4 (and E4) are conveniently tucked away yet easily removed.

The useful detachable tweezers on the Squirt E4 and S4 tuck away into the tool efficiently and could easily be missed if you were not aware they were present. They are easily extracted, unlike some of the alternatives

I like the extra medium sized screwdriver on the Micra and S4 though I do wish it were an awl instead. If it were exchanged for an awl that would remove my often used bottle opener. I prefer the dedicated thin eye-glass screwdriver over using the less convenient flat Phillips tip. However the Style CS offers a small but useful toolset, is the thinnest of the Leatherman keychain multi-tools and weighs less. The lightest Micra is 49.9g, Squirt S4 is 52.3g while the Style CS (still available for purchase by the way) is the lightest at 41.7g.

My biggest preference other than my essential two tools is the ease in opening tools from the outside with no need to unfold the entire multi-tool. So, for me, it narrowed down to the old, now discontinued, Squirt S4.

Carried in my ditty bag, one of these great little multi-tools has accompanied Three Points of the Compass on well over 3000 trail miles over the years. While I do occasionally swap it out for a different knife or multi-tool, seeing if something else works for me better (usually trying a 58mm Victorinox or Leatherman Style CS), I constantly find myself returning to the old favourite S4. Perhaps I need to find a spare on the second-hand market in case mine should ever get lost on trail somewhere. If only it also had a can opener and that awl…

Leatherman Squirt series

User guide for the first three tools in the Squirt series, 2006

2006 user guide for the first three tools in the Squirt series, the S4, P4 and E4

The first Squirt series

Eight years after Leatherman released the Micra, its first keychain multi-tool, it released two more. In 2002 the stainless steel framed, aluminum anodised Squirt S4 and Squirt P4 hit the vendors shelves. The S4 had scissor jaws while the P4 had a small set of pliers.

Leatherman Squirt S4

My Squirt S4 was made in 2007 and I purchased it the following year. It has remained a frequent companion on the majority of my hikes since then. I have swapped it out on occasion, most usually for a Victorinox, but I have usually found myself promptly returning to it. I really appreciate a full size set of good scissors. Beside the desired blade, as a glasses wearer, it is probably the extra small screwdriver that has seen most use, that and the bottle opener with numerous bottles of beer. On longer hikes the nail file has been useful and I have successfully worked on stove repair and changing internal trekking pole mechanisms with the screwdrivers.

Leatherman Squirt P4

The Squirt P4 is not my favourite keychain tool because of the lack of any scissors at all. But beside pliers, blade, files and various screwdriver heads, instead of the tweezers found on both E4 and S4, the P4 does include a short little awl. This implement is not particularly sharp when purchased new. In fact it is positively blunt. However it can easily be sharpened up. This is useful for poking holes in belts or fabric, even as an extra little blade. I am not one for modding my multi-tools but if I were, I would be stripping the P4 down in an attempt to swap this awl out with some tools on other Leatherman tools that I find less useful. Both the Squirt S4 and P4 were available in grey, yellow, orange, pink, black, red, blue, green and purple.

A short but useful awl is found on the Squirt P4. This is the only one of the Leatherman keychain tools to have this, a shame, as it would be a great addition to others in the line

Leatherman Squirt E4

In 2003 Leatherman followed the S4 and P4 with the Squirt E4. First available in bright ‘inferno red’, for a year or two, the E4 could only be purchased at one of the Radio Shack outlets (branded as the Squirt EL). In the UK, it may have been available through their Tandy stores. These small shops were aimed at the home hobbyist and electricians, this was the market that Leatherman were attempting to tap with the E4. After a while, availability spread to other outlets and ‘glacier blue’ and ‘storm grey’ colours were added to the range. Mine is in the latter colour.

Tips of electricians (left) and normal pliers (right) compared

The electricians pliers are fitted with efficient wire strippers and a useful needlenose plier tip. Back tools include file and blade, however, no scissors. Not only do I complete very little electrical work on trail, with both Squirt P4 and E4 lacking scissors of any size at all, neither of these tools is going to make it out on to a hike with me.

The Phillips screwdriver on the E4 is a thing of beauty. Incredibly well formed it is a proper 3D shaped screwdriver tip that folds away in to the tool well. However I have found the 2D Phillips tip found on other Leatherman multi-tools more adaptable in practical use. Not only fitting a wide range of Phillips heads but also can be used on a small range of slot screw heads too. The 3D Phillips head is only found on the Squirt E4.

All three of the first Squirt series were discontinued in 2010 to be followed by two replacements.

Few hikers would actually hand a Leatherman, or any knife, from a keyring. A split ring attachment is often superflous. If the ring is attached, the key ring attachment can be swung round and tucked out of the way

The second Squirt series

Leatherman Squirt PS4

In 2010, hot on the heels of the discontinued Squirt S4, P4 and E4 came two revamped replacements. These were the Squirt PS4 and Squirt ES4.

The two tools pulled together the most popular elements of their forerunners. Effectively, each carries the same toolset other than the Squirt PS4 having standard pliers and the Squirt ES4 ‘Elektriker’ having electricians wire stripper pliers.

I would anticipate the PS4 having far greater sales over its brother. You shouldn’t simply write off the electricians pliers however. The useful quite thin electricians tip is capable of quite fine work such as pulling thorns and splinters, though it would be even more useful if they were truly needlenose tips.

Leatherman Squirt ES4

It was a very clever combination of tools that Leatherman managed with these two multi-tools, they really learnt from the earlier incarnations, this despite my personal preference that a few other aspects had been retained instead.

Both Squirt PS4 and ES4 were released with blue, red and black anodised aluminum scales and are still being manufactured today.

The two sides of the files found on the P4, E4, PS4 and ES4 Squirts compared. You can see the toothed edge to the file that can be used for notching wood, sawing plastic and not much else. Each of these tools has both file surfaces

While some of the mini Leatherman multi-tools have wood/metal files, that can be used as nail files, others come with dedicated nail files. All of these actually do a pretty good job and there is little to choose between them. Each nail file has either a nail cleaner or small flat screwdriver tip, though these will not handle a lot of torque.

This was a great series of small multi-tools from Leatherman. How could they follow it? By stripping them down to the essentials and adding a little style, that’s how. I shall look at what followed in the next blog.

Knife chat: Leatherman keychain multi-tools: which is best for hiking?

A choice of nine keychain multi-tools…

Three Points of the Compass likes to carry a knife on trail. This is most often used for food preparation. However I have found that the most useful tool by far is a pair of scissors. I have used these for trimming nails and skin, cutting plasters, bandages and gauze, opening packages, Mountain House and a myriad of other tasks. These are the two tools I want with me on any folding knife or multi-tool when backpacking. Any other tool is a bonus. That said, if I am not going to simply take a Victorinox Classic SD with me, then whatever tools are on a multi-tool, have to add something that the Victorinox doesn’t deliver. I look here at what the smallest of Leatherman keychain tools has to offer the hiker.

The ditty bag/repair kit that Three Points of the Compass carried on the Cape Wrath Trail in 2018. A Leatherman keychain multi-tool formed a vital component of this

Various Swiss Army Knives have proved themselves fantastic for taking hiking, others less so. I am also a big fan of the small ‘keychain’ multi-tools produced by USA company Leatherman over the years. Some have been carried on my backpacking trips and I liked, and again, others less so. There is one little Leatherman in particular that is usually stuffed into my ditty bag or First Aid Kit and has been carried with me for thousands of trail miles. I’ll come to which one in a later blog in this series. But I thought I would spend some time here looking at some of the very small multi-tools produced by Leatherman over the years that incorporate both my desired scissors and blade. Particularly as some of these models are now discontinued and beginning to get harder to find.

History

Leatherman began making multi-tools in 1983 when it released the PST (Pocket Survival Tool). At their release Three Points of the Compass looked at these new offerings in the outdoor gear shops and wondered why anyone would ever want a pair of pliers on their knife. Having purchased one out of curiosity, it subsequently got me out of a fix on many an occasion, but only at work, it was never taken with me when hiking as it was simply too large and heavy.

Just three years later, in 1986, Leatherman shrunk their tools and released a new smaller model, that was the MiniTool (in production until 2004). However that had no scissors and at 114g was no keychain tool, it didn’t even have a ring for attaching it to anything. It was what it was named- a mini tool, with fold handles to make it full size. I actually purchased one when they were released and worked it into the ground, another of my multi-tools that never survived the years.

Leatherman have released a huge variety of tools over the years, they continue to do so, always seeking out another niche market or tweaking existing tools for the collector market. In 1996 they released the first of their keychain multi-tools. This was the Micra. So popular and successful was it that it is still manufactured today. On the back of this popular product, Leatherman went on to release another eight keychain models, the most recent in 2011. At the time of writing (2019), five of the keychain tools are still manufactured new and are available for purchase. The retired models can still be picked up on the second hand market, though one or two are beginning to get scarce.

The nine keychain sized multi-tools released by Leatherman

Nine Leatherman keychain tools- the Micra, Squirt and Style series

There have been nine key-chain tools released by Leatherman over the years. All but one, the Squirt E4, would make a great little multi-tool for taking on trail. The intended user of the E4 is not me, it being aimed more as a pocket tool for electricians. The tool was produced in much smaller numbers and is now quite difficult to find. Despite owning one I am not a great fan of it and any of the remaining eight keychain tools would make a better choice for taking on trail.

Below, I cover the primary tools- scissors, blade and pliers and subsequent blogs over the next few days will look at some of the more specialised tools built into the various tool ranges.

Scissors

There are seven tools with scissors in the range of Leatherman keychain multi-tools, These are the Micra, three in the Squirt series and two in the Style series. All seven are shown below. There are two major differences in these scissors.

Three tools have quite large, reasonably powerful and efficient spring-loaded scissors, using cams and back-springs, as their jaws when the tools are unfolded. The scissors on the Micra are a very slightly different form to those on the Style CS and Squirt S4, more akin to the scissors found on Swiss Army Knives, however all three are equally efficient at cutting.

The remaining four have small scissors, akin to those on the Victorinox Classic, that are accessed from the back of the multi-tool when still closed. Each of have a captive torsion spring, though to a lesser efficiency than their spring loaded larger cousins. The scissors can be opened wide to enable resharpening. The springs on these smaller Leathermans are more robust than the scissors found on small Victorinox multi-tools such as the ubiquitous Classic. They will still break though, especially if put to too heavy a task. Leatherman will fix these under their excellent warranty. The remaining two keychain tools, the Squirt E4 and P4, do not have any scissors.

Blade

Eight of the Leatherman keychain tools have blades, the Style PS is the exception. In theory, this means that the Style PS can be taken through airport security. There are many accounts of this tool being confiscated however so I wouldn’t recommend it.

Blades are made from 420HC stainless steel, chisel cut, which can annoy some users but I have never had any trouble with them. They come with a good edge from new and can easily be sharpened. The steel will retain an edge for some time. I do wish Leatherman had produced an option of 154CM steel as they have on some of their other, larger tools.

Blade length is 41mm (1.6″) however not all of this is usable length. Flat cutting length is only some 27mm (a little over an inch) however there is another 10mm or so of curved bade beyond this. It is usually imminently sufficient for most tasks while hiking or around camp. Note that this is all very easily within UK legal requirements but as is now usual, you are never going to be allowed to fly with this.

Most blades are of approximately similar depth though this will alter slightly over time as they are periodically sharpened. My Style CS is 8.45mm while my Style is 9.15mm at widest depth reflecting the greater use and consequent sharpening of the former. The slight notch at the base of each blade varies slightly in depth, being most pronounced on the Style and Squirt S4 where it can most effectively be used as a thin wire bender or possibly wire stripper.

Because of their small size, food can gunge up one of these tools pretty easy, especially the holes in the blade on the Style range. Leatherman CS in use on the Tabular Hills Walk, Autumn 2019

The size and nail nicks on the blades varies a surprising amount. The holes on the blades in the Style series are there for aesthetic reasons only. Food, especially cheese, gets stuck in the holes and the nail nicks were moved down the blade to accompany them, to the tools detriment as the blades are consequently harder to open as a result. More recently it appears that Leatherman have begun to put standard blades into the Style, this is a welcome change.

Only apparent differences are minor styling on the Style blades, size and position of nail nicks, and a slight drop point to the Micra blade. All are made of the same quality 420HC stainless steel

None of the blades lock, so a little care has to be taken when using them. I much prefer the ease with which the blades can be accessed on all of the Leatherman keychain tools other than the Micra. The Micra has to be opened to access all tools, including its blade, from the inside. As to the other eight tools, if pocket carried, fluff and general crud can build up under externally positioned tools more easily than with the Micra, however I have never found this an issue. On trail I don’t carry one in my pocket. More commonly you will see hikers hanging one of these tools from a pack’s shoulder strap daisy loop, however I prefer to keep it in my food or ditty bag.

Pliers

There are many hikers that feel a pair of pliers can be particularly useful on trail. Three Points of the Compass is not necessarily one of them. There are certainly times when they can be useful, if not almost indispensable. It can be difficult to repair a zip without pliers and lifting a pot off a stove is often easy with pliers. Pushing a needle through tough cordura or leather is made far easier with pliers, though a rock could be used with care. It is all about determining where your particular emphasis, needs and wishes lie. Myself, I prefer full size scissors, however others may feel a small pair of scissors suffice which frees up the opportunity to potentially include pliers tips.

There are three choices of jaw in the small Leatherman keychain multi-tools. These are scissors, pliers and the less useful electricians pliers. All use backsprings and cams and are very efficient for lighter tasks

Two types of pliers can be found on the Leatherman range of keychain sized multi-tools- these are the needlenose pliers on the E4 and later ES4. These also have regular, if small, pliers in the same head. The two Electricians’ tools, the Squirt E4 and ES4, have needle nose pliers, wire/hard wire cutters and wire strippers- 20GA, 18GA, 16GA, 14GA and 12GA.

If taking a multi-tool on trail, any of these have numerous crevices in which food and gunk can accumulate and fester. A decent periodic clean will help reduce the chance of cross-contamination

Colour

It is pretty obvious that on trail, a brightly coloured knife or multi-tool can be a preferred feature. Put any item of muted colour down in the long grass and you asking to lose it. It is one reason why the classic red Victorinox Swiss Army Knife is a great choice for backpacking. That flame red sticks out like a sore thumb. That said, Three Points of the Compass does like muted colours, you will not see me wearing bright reds, orange and yellow. I like to blend into my natural surroundings. Whatever your choice, many of the Leatherman key chain sized tools came in a variety of colours, especially the Micra which has received numerous scales and wraps over the years. Even the diminutive and minimalist Leatherman Style, which only enjoyed a four year production run, came in four colours- black, red, blue and pink. If you want a really brightly coloured option, one of the few keychain tools released by Leatherman with pink coloured scales is always going to stand out.

In 2012 Leatherman announced their Pink Program- this was their support for breast cancer awareness and they released three of their tools in a striking pink colour. These were the Micra, Style and Style CS. Each of them features the breast cancer awareness ribbon laser etched on to the blade. The Micra and Squirt also feature the ribbon on one of their scales. Note that not all pink Leatherman tools were part of the Pink Program and not all have the ribbon feature

Future blogs will look more closely at some of the other tools found in the various ranges. I shall end with a particular recommendation from this useful little selection of small multi-tools.
