Can someone shed some light on when the early lockup fad started? Both of my Hinderers are no more than 10% engagement, and my buddy's is maybe 5%. He's almost scared of it, and I'm not the biggest fan. He used to sit and flick open his XM as hard as he could to try and get the lockbar to move over some. If you complain about their early lockup, you're usually ridiculed for not sharing Rick's vision of the frame lock though he was not the inventor. My XM's seem to have a lot less spring tension than my CRKs as they don't take very much pressure to disengage combined with the super early lockup.I have to say I think early lock ups are a fad among the knife community. As long as it's not touching the other side, locks up solid and doesn't move over the years, so what if it's at 75 or 80%?
The Spyderco frame lock or liner locks I've experienced including the Military, Sage 1 and 2, and Southard have all had perfect engagement of around 50% where the lockbar is completely engaged.
Both my Sebenzas are about 50 to 60% I'd guess with no movement since I've had them. The thing is it doesn't really bother me since I know if it ever became a problem, it'll be taken care of. If I didn't think it would be I'd never spent the money on them in the first place.
