There was no comparison. The CRKT was more expensive, made from inferior steel, came with a thick, obtuse, and dull edge, and had a curiously wobbly pivot that the instructions indicated was supposed to be that way. The smaller P.E.C.K. was the same, with an edge bevel thick and obtuse enough to look like it might have been on a hardware store hatchet rather than a tiny, keychain sized folding knife.
Shecky, could you show some pics of the CRKT 420J2 K.I.S.S.? just curious. Thanks(Can anyone confirm which steel the blade is made from. Many sites say AUS 6M yet others say 420J2)
