Believe it or not, nearly all instances were due to manufacturing/material defects, which one would probably expect from the cheap "Made in China" models (that seem to make up much of the selection at various summer camp trading posts, sadly), but also from mid-range companies (e.g., Gerber, CRKT, Buck, Benchmade, etc.). I've spent lots of time replacing blade stops and washers, and properly file-fitting locks on "trading post" knives after summer camp in an effort to provide the Scouts with a folding knife with a bit more safety. Of course, I quickly follow this up by showing them a $10 fixed-blade puukko-style Mora (or equivalent) that probably cost less and is more reliable than the finger-guillotine I just adjusted for them.
