I recently came across an unusual blade design. Actually the design itself wasn’t so much unusual, as much as the way in which it was used.
The SOG spirit knife is essentially a small spear point blade, attached to a short handle. The handle is detachable, and the blade itself can then can be attached to a shaft, in order to make a spear. Or you can leave the handle on and use it as a small knife. They even suggest that it could be used as a throwing knife.
The short spear point design is unusual, but I can see the usefulness of the design. It would be work well as a small knife for fine detail work, such as carving whittling, and such. However as a survival tool, I think the design is too limiting. For instance, I can say, with a pretty high level of certainty, that I would not be throwing *any* of my valuable knives at anything, if I were in a self reliance scenario.
The same for using it as a spear. You can make 100 disposable spears and/or throwing implements with a single good knife. A good knife, on the other hand, is hard to make out in the field. The thing is, if you lose your knives, and you’re much more liable to find yourself in great big world o’ hurt. So that kind of rules out half of the proposed use cases for this design.
The other thing, as I’ve mentioned in past survival knife posts, is that I consider both detachable and folding blades a liability. Detachable/Folding = weak = easily broken or lost. I would much rather have a small, full tang knife for fine work, than something like this, that is liable to work loose, or break off even, and get lost somewhere.
So ultimately, at the end of the day this may be a good knife for casual outdoorsman stuff, but for a good self reliance/survival tool, I’d probably look elsewhere…
