The pectoral position is a very useful position to carry a knife. It is accessible with either hand, and if the wearer is seated or prone. It can be readily utilized to cut a jammed seat harness, or when rolling on the floor with an aggressor.
This topic came up in one of my discussions on soldier’s load. Modern servicemen have a lot of gear to carry, and many do not believe carrying multiple knives is warranted. If you are going to carry a single fixed blade knife, then the weak-side pectoral position is a good place to place it. This influences the form of the “pec-knife”. Pec-knives are discussed in “Survival Weapons”, and their use in “Crash Combat”. The more general discussion of knife use for defence in “Attack, Avoid, Survive” are also relevant.
You sometimes see quite large knives carried in this position, but for most of us an overall length of less than eleven inches is more practical. There is a wide choice of fixed blade knives in this size range. Harder is finding a knife of sufficient thickness and robustness. If this is going to be a soldier’s primary blade then it must stand up to some rough treatment.
A few weeks back I encountered the Gerber Strongarm. This just seemed to shout “I will be a great pec-knife!” Just before Christmas I got an email telling me the variant I wanted was back in stock. Money was short, but I had had a rotten day and a few minutes before midnight I gave into temptation and ordered a Strongarm. It helped that the price listed was about 30% less than most other stockists! Would you believe it? I looked the next day and the price had jumped a big chunk. I had ordered just in time! A few days later the Gerber Strongarm arrived. I wish I had had the money for another, but as it is I may run out before the end of January. Buy books please, people!
The Sheath and Extras
An important component of a potential pec-knife is the sheath. This mode of carry is most convenient with the knife inverted and the pommel downwards. Obviously it is necessary that the knife is fully secure in this position, but still capable of being easily drawn when needed in a hurry. The sheath of the Stongarm has a large clip that engages a depression on the hilt. Note that this releases with an audible click, which may affect your tactics in some scenarios. In addition to the clip, the smaller-width hanging strap has a retention strap with a popper. The latter feature is one of the few I have issue with. This is a little tight, the slight increase in grip width my lanyard has added making it sometimes fiddly to close. The length of strap past the popper is also on the short side, and may be difficult to pull on if wearing some gloves. It may be necessary to sew an extension onto this part.
An important feature of this sheath is that it is ambidextrous, so the knife can be inserted securely with the edge either to the left or right. This is useful for a pec-knife, it being considered to be prudent to carry your knife with the main edge outwards, away from your throat.
A couple of accessories are included in the box. I have already mentioned that the smaller-width belt hanger has the retention strap. This affixes to the sheath by a strap and popper. A larger width belt hanger can be attached to the smaller by poppers. Both belt hanging loops have poppers, making the easy to detach or attach without rethreading a belt. A device that allows the sheath to be mounted horizontally is included, as is a device allowing easy attachment of the sheath to MOLLE/ RALS systems.
The knife itself comes with either a semi-serrated or plain edge, and is available in either black or a more practical coyote brown shade. The blade is 4.8 inches long, and 3/16th thick. Overall length is 9.8 inches and weight is given as 7.9 oz. Blade material is 420HC stainless steel with a dark grey coating. Grip is a rubber coating over glass-reinforced nylon. There is a resemblance to Gerber’s LMF II knife. The LMF II is heavier (c.12 oz) and costs more. I have not handled a LMF II, but the Strongarm seems a better choice for the pec-knife role.
The butt of the Strongarm ends in a blunt triangular point that might serve for applications such as window breaking. This feature is thoughtfully provided with a lanyard hole. I know I have said this before (yesterday actually!) but it really is surprising how many expensive knives are not provided with provision for a lanyard or other features to reduce the chances of loss.
Making a Chest Rig
There are plenty of good reviews of the Strongarm out there, so I will concentrate on specifics of rigging it as a pec-knife. This is actually very simple. Obviously, you can mount the sheath directly on your webbing, but what if you are not wearing such? The Strongarm is potentially a very useful knife, and you may want it when you are not in full tactical gear. I have seen the Strongarm described as a “cross-over” knife, good for urban and wilderness.
Take about two metres of paracord. I know frugality is a virtue, but it is prudent to have a little too much rather than start again. The Strongarm sheath has a number of “screwholes” down each side. Pass one end of your paracord through a hole near the sheath mouth, and the other through a hole on the opposite side, second from the end. This should be made clear from the photos. Experiment with what arrangement suits you personally. Pull both ends of paracord so the middle makes a snug length across the front of the sheath. Now take both lengths, hold them together and tie a single knot in both. This can be an overhand knot but a figure-eight may be more comfortable when worn. You should have created a large loop with the knife sheath threaded on it. This loop should be large enough to pass your weak-side arm through, the knot sitting somewhere between your shoulder-blades. Take the long, free ends and form them into a second loop using the knot I call a “slip-bend” in my free book on knots. Place your other arm through this loop and tighten it by sliding the two parts of the slip-bend apart. The Strongarm sheath should be hanging just before your weak-side armpit. If you have the small-width belt hanger still attached this may be used to anchor the sheath to a belt, if you wish. Note the snap-link, added by a magnus-hitch. The lanyard can be attached to this when greater security is wanted. It also proves useful for holding other items. I later relocated the snap-link to below the sheath, where it helps keep it in position.
A chest-rig for a knife can cost tens or hundreds of dollars. This one is simple, lightweight, comfortable and costs just a couple of metres of paracord. If you like this, throw some of the money you have saved this way!
