these are WAY bigger than they need to be, but case in point:
in a full grip, my index finger is 1/2" away from the cutting edge, and I could decrease that to 3/8" if I wanted to spend the time sharpening that last bit of ricasso side edge. I've got all the control I need over the object being cut. If I need "more control" I can comfortably grab the guard.
The second is a modified HI ang khola. It's not entire fair to use it as a comparison because the distance from the index finger to the blade is 2", nearly twice as far as most models of busse (save for maybe the fbm series). However, it shows how much
less control I have in a full grip then if it was choiless.
The difference between the original and modded versions of my sus scrofa may not seem like much, but it is significant in use. The distance from the edge has been reduced from 1" down to 1/2", and could be brought even closer with a little more time sharpening. Where before I had 1/2 from the pommel to my pinky and another 1/2" from my index finger to the edge that wasn't getting used 99% of the time, now I have the maximum edge in the smallest size package possible from this model.
With the boss jack series, the distance is even more significant because the choiless versions main grind is brought farther towards the handle slabs. This means you have even more control in the full grip than on nearly any other choiless busse to date. You are getting the maximum amount of edge possible for that size of knife, with minimal wasted space between your index finger and the edge. Cut off the butt and you've got a
compact design for it's size, something that is uncommon in the busse lineup.
