How burly is the FRN handle with lockback as done on many of the Spydercos? Also, does anyone have problems with the Spydies that don't have an adjustable pivit pin? I have just begun getting into knives, so here are my limited experiences. I own a BM 710, a Buck Odyssey, and a Spydie Military. The overall construction and lock of the BM seems totally bombproof for a fairly light folder. The Military's construction is lighter weight, and hence, weaker, but I am willing to live with that. The liner locks seem a little sketchy. The Military lock fails with moderate spine whacks. The lock on the Military also loosens up when gripped tightly. I believe this is a trade-off of having an easy-to-release (possible with gloves on) lock. How does the Spyderco FRN/lockback format compare with the knives mentioned, and in general? Thanks in advance. Nail_dude
