Why does only the lower section of the lock bar contact the blade on Strider Folders?
Per Mick Strider:
"The reason we only want contact at the lower section of the lock bar is this:
1. For the most solid lock, you need two points of contact, as far apart as possible. (bump stop and lock face)
2. For the most solid lock, your lock contact should be as far away from the center line of the pivot as possible. This keeps your lock from "rolling" off the blade.
3. No matter how far from the pivot center your lock surface is, if its contaminated with crap (sand), it will fail. We send knives into some nasty sh**. This is a huge concern for us. By making contact at the lowest section only, it creates a "sh** vent" above the lock surface. That is the same reason we make our detent hole go all the way through the blade....its a "sh** vent"."
