I was wondering, though... why do you put the little rounded hole bit thing (english failing me) in the hook pick, just after the handle finishes? for looks or functionality? is it somewhere to put a finger?
It's something I started to incorporate into the tangs awhile ago. The cut out is a relief so flex can be adjusted without sacrificing the tangs width of itegrity.
So say you have a kwickset that is new, and one that is used for a while, you can use diffrent degree's of flex points to match the lock.. and you do need to sacrfice width which is never a problem with proper finishing.. but in comercial crap look out

hope that helps
