I hear ya' James! Everyone needs to post their preference and, if possible photos to back it up or an explanation as to why they think a (5,6,7,or8) would be best. As James and others who frequent this forum already know, I use a #3-5" and a #5-5" an awful lot..."BUT"...(Aahhh: Got that in early)...I "hunt"! If I were using my model #5 as a "strictly camping" knife, I may want to switch it up and go longer.
It will be interesting to see how this build will go. The Model #5 offers as many blade lengths as any individual model...(Model 2 as well).
Best, Capt. Chris
