That's my complaint about the Smock, where the choil not only takes over a significant portion of the edge but also has a (to me) "dangerous" upright leading edge.
Compared with the Smock virtually nothing is lost to the choil on the Amalgam, given the 1/2" difference in the length of the blades.
PS: In response to others, I've never had a "lock stick" problem w/the Amalgam or any other Spyderco compression lock knife. The blade always drops free and, even if it has a flipper tab, I can just release the lock and flip it open w/a flick of the wrist.
PPS: It's about time to rotate the Amalgam out of my pocket. Not because I don't like it but because other knives deserve my attention.
Think I'll replace it w/the Tropen - another of my favorite Spydercos - which has all of the features that people either love or hate . . . a 4" upswept blade, flipper, compression lock, Emerson type tab opener and the fearsome 1/2" partially exposed blade that critics go on and on about.
Personally, I love it.
