One thing I should mention, I will not be modding the BOSS to give it a convex edge prior to the competition. This test is to see which one I like better in its "natural" configuration.
While a RAT 4 may be more similar to a BOSS, similarity isn't the point here. The Bravo 1 is the best bushcraft/survival knife I own and I want to see if I can one-up it. The RAT 4 and Fallkniven F1 and S1 already lost in previous field tests, so this is just a one-on-one competition.
Here's a preliminary list of test factors I'll be considering:
Bulk
Cutting geometry
Balance
Ergonomics
Ease of sharpening
Edge retention
Corrosion resistance
Notching
Batoning (with cutting edge)
Batoning (tip-first)
Chopping
Slicing
Prying (light only - this isn't a destruction test!)
Stripping (bark and branches, not shirts and underwear)
Firesteel striking
Any ideas for additional tests?
