Many people have ideas of what determines a “good” knife. Size, blade shape, bevel of the grind, full tang, etc. While all these are important for various reasons, the most important aspect of a knife is to have one.
The knife in your pocket on a day-to-day basis is likely the knife you will have when it matters most. No knife? That’s gonna suck. Wrong knife? That may just require an adjustment in outlook. Let’s look at different tools with the different applications in which they could excel.
BUSHCRAFT
Fixed blade of 3 to 6 inches, straight-edged for at least half the blade length, with decent belly for skinning, optimum grind of Scandi bevel, full tang, and good grip for wet hands. Sharp squared spine for use with fire steel, blade thickness of 3/16 to 1/4 inch, and high quality carbon or stainless well-tempered.
Must be able to perform fine carving (fuzz sticks), skinning of small animals on up to deer, batoning of larger wood or notching (trap triggers), hold good edge and sharpen easily (as in not D2 tool steel).
JUNGLE
Mid-length machetes, kukris, parangs, bolos, and the like are well represented world over. The heavy cover of jungles requires a larger blade to enable efficient work. Again, full tangs and edge holding/sharpening is paramount.
URBAN
A good multitool cannot be overlooked for the urban survival situation. The need for various screwdrivers, pliers, saws and blades, as well as the everpresent bottle/can opener can be very real in the concrete jungle. While a multitool is always a good addition regardless of the environment, it is unbeatable in the city.
COMBAT/TACTICAL
Don’t bring a knife to a gunfight (21 feet is rare exception). Having stated that, knives don’t jam, misfire, misfeed, run out of ammo, or have punishing recoil. When facing a rough spot, the best knife is to HAVE A KNIFE. Fixed blade or folder, straight edge or serrated, single or double-edged, big or small, shiny or flat, ad nauseam, the type must be compatible with the fighting style.
NOW THAT WE ARE GOOD AND CONFUSED…
What kind of knife should you have? Depends on where you are, what needs are to be met, and the possible requirement to avoid unwanted scrutiny (LEO’s). In the end, there is no ONE perfect knife. Having a few to choose from (or back-ups) and different types for different needs seems to be the best idea. Quality should be sought after, but don’t confuse high cost with quality. Above all, don’t go for the wow factor “it was in the movie” or “it’s just like the one (insert survival celebrity here) uses”. It may be the one Granddad gave you when you were twelve.
What we do and why we do it, better with a blade.
