The greatest disappointment about any Mora knife is the sheath: a flimsy, plastic thing that won’t easily fit on a decent sized belt and does not even hold the knife very securely. As they come, I consider them unusable. But a few simple modifications and additions make them quite acceptable.
The Mora knife sheaths are designed to be mounted either on a button on a pair of coveralls or through a belt. Apparently people wear very small, skinny belts in Sweden. Over here in the United States of Gun Belts, that doesn’t fly. The belt slot on the sheath can be forcefully enlarged by shoving in a piece of wood, such as a ruler, and applying heat to cause the plastic to expand, but I don’t trust that such an act will not over weaken the plastic. I’m not a big fan of carrying a Mora directly on my belt, anyway. Usually, I’ll carry the knife either on a lanyard around my neck or as a dangler off my belt. But both of these setups allow the possibility of the knife and sheath to swing freely, accentuating the problem of an insecure fit.
Both the problem of how to carry the sheath and the problem of the insecure fit can be addressed with a single piece of paracord.
With the knife in the sheath, I take a piece of paracord and run both ends around the handle and through the slot for the belt. Then, tight against the back of the sheath, I tie an overhand knot in either end of the cord. This creates a loop of paracord on the front of the sheath that can be made smaller, but cannot become any wider than the bottom third of the handle. Because the handles on Mora knifes are somewhat tapered — fatter in the middle than on either end — this loop prevents the knife from being removed from the sheath. Even if the knife is only lightly dropped into the sheath rather than securely pressed, it cannot be removed without first sliding off the loop of paracord.
After tying the two knots against the back of the sheath in either end of the paracord, I take both ends and tie them together, forming a loop on the back of the sheath. This provides my carry options.
If I want to wear the knife around my neck, I take a pre-tied loop of paracord that I carry and loop it through itself around the loop on the sheath.
To carry the knife in a dangler system, I prefer to use a Maxpedition Keyper rather than a carabiner. The Keyper is mounted on my belt and clipped into the loop of paracord on the sheath. (To reduce movement in this setup, I’ll stick the knife and sheath in my pocket.)
The last thing that I do to this part of the sheath is add a small wrap of electrical tape around the very top, covering the upper bit of the belt loop and the button hole. This prevents the paracord from sliding to the top of the sheath and forces the securing loop to be about .75” from the very end of the handle. I’ve found that if this is not done, the securing loop is like to slip off the handle.
That’s all that is needed to make the sheath usable, but a few other additions can be made to increase its utility.
Around the top of the sheath, I wrap tape. In the sheaths pictured here, one has 2” olive drab duct tape, the other has 1” black Gorilla Tape (which is like duct tape, but thicker and stickier). One can never carry enough tape. I imagine, also, that the tape likely increases the structural integrity of the sheath.
On the back of both sheaths, I have a #17 sailmaking needle, pre-threaded with black kevlar thread, taped down with some electrical tape. As I mentioned in my review of the RAT Izula, this is an idea I first picked up from one Dave Canterbury’s videos. The extra needle and thread adds no noticeable weight and could be a welcome addition to the sheath if you ever find yourself separated from your pack, with the knife and sheath as your only piece of gear.
The next modification on the body of the sheath was also inspired by Dave Cantebury. In another of his videos, he showed how he had layered different width pieces of inner-tube on a machete sheath to create pockets that could store small items, such as a sharpening stone and magnesium fire starter. With that in mind, I add a wide piece of inner-tube onto the middle of the Mora sheath (which also serves to cover and further secure the taped down needle). Then, on top of that, I put a skinnier piece of inner-tube. Slid between both pieces is a backup ferro rod. Because the rod has rubber below it and rubber atop, there is an incredible amount of friction. The ferro rod becomes difficult to remove. I have carried blank rods in these “pockets” and they have never fallen out. Still, I prefer to carry rods with a lanyard of some sort on them. I loop the rod through its lanyard around the paracord loop on the top of the sheath, guaranteeing that the rod is secured.
The sheath for my KJ #1 knife has only a ferro rod. That knife is carbon steel and can generate sparks off the spine. On the sheath for the larger SL-2, however, I have added a small striker slid between the two pieces of inner-tube on the back. The SL-2 is made of laminated steel, which is too soft to reliably produce sparks.
These modifications made to the Mora sheath help to secure the knife, allow for different carry options, guarantee a source of fire, and provide a needle, thread and tape for repairs. They turn what is otherwise a near useless sheath into a functional item worthy of being matched with the Mora blade.
(I also own a high-quality leather sheath made by JRE Industries for the KJ #1 knife. I tie a loop of paracord through the top loop of leather on the sheath so that the knife may be carried around the neck or on a dangler, similar to the modified plastic sheath. The leather sheath does not require a loop of paracord on the front to secure the handle. Nor does it need pieces of inner-tube to create a pocket for a ferro rod. The only thing that it lacks is a repair needle, but I have found that most tape does not adhere very well to leather, so I cannot stick one on the back.)
