i get the impression the bolt is just the poly handle version of the torch, at least my understanding, I brought a bolt to bear camp this spring and another guy did also, we did 8 bears, never snapped a blade, cutting paws off, skinning out the paws, etc. I tested mine quickly before the hunt on a badger that a buddy bowkilled and was in my freezer so I cased it and sent it in for tanning, cut head off for an uncle who wanted the skull etc. and no issues...what a great little knife, one guy in bear camp who has skinned and cut meat at cattle plants for years and years and guided/hunted whole life etc. was very skeptical of the bolt as he was very used to knives and particular as you can imagine, his bolt is on the way as when handed one for splitting lips and doing paws etc. he was sold right away, not sure he will still skin with it but doing heads etc. he will and he always does whatever he can to get game into his garage for boning to use the 6" traditional boning knives to which is amazing to watch him work in that atmosphere, me and the other guy who brought the bolts were first time users and both came away very happy and can't wait to get them on some ungulates in fall, I did the badger with one blade, I think smaller bears around 2 blades and bigger bears up to 3 if that's any help
the bolt with the 60a blades = awesome, mine weighs 1.5 oz naked, then case is 1/2 oz and another 4 blades in case is half oz, I picked up a leatherman style at 1.6 oz to throw in case with it for blade changing and all total we're talking 4 oz with the works....that's pretty good, if you consider each blade a fresh knife then we are under 1 oz per knife that way and it drops with every blade you add....not that weight is an issue bear hunting where we did but for the sheep/mountain nuts its data we like
