Hi, Josh...glad to see this thing coming around... It's not for me, but it's your baby, and you've been around the horn and know first-hand what most folks want in your fixed blade for heavy duty... My best advice is to use your own head; folks will buy it. I'll be interested when you come up with a smaller fixed blade that I can carry cross-draw... no swedge only make a small sharpening choil no bow drill recess the thumb ramp looks aggressive, but you're the master, so you know what's good. ferro rod placement ...forget it. Size ok? NO... Josh, I am a big fan of fixed blades, but I like 'em about 3.25-3.5"... the grip is MUCH too long for my large hands, even if wearing a glove...a grip about 4.4" bare-handed is about max for me, and even the model 21 large Sebenza is a bit too long in the grip for my large hands... Of course, I've asked CRK for years for a medium Sebbie, to no avail. cheers, Don IMO the blade is quite a bit too "high." I know it's meant for beating but this particular blade "height" seems to be larger than could ever be of use...even under abusive means. Your blade thickness is "up there" and speaks to your intended use; it's your design, so go for it... I do vote for a thin BTE measurement, but you know all about that better than I do...I prefer about 0.010" BTE.
