As we endure the reign of the TFF for what now is the second decade, its time to look at things that could be done to improve the King of Locks. Over the years since the first Chris Reeve Sebenza, the titanium frame lock has come to dominate the custom market. Aside from fixed blades and slipjoints about 90% of the locks on customs are frame locks. If you exclude the high end art knives that number rises to about 95%. In all that time there have been many iterations and improvements on the frame lock.
The Overtravel Stop:
Frame locks rarely suffer catastrophic damage. When they do, it usually has to do with the lock bar coming out of alignment-either overflexing outwardly ending or getting bent up or down too much. Either way, without something to prevent the lock bar from swinging out of alignment, the frame lock, at least in theory, is susceptible to knife-ending damage. Rick Hinderer invented the overtravel stop. You can find them on all of his knives and all of the ZT collabs he did including the pretty decent ZT0562. This small button shaped stop on the middle of the lock bar ensures that everything remains exactly where it should be. The result is a much more stable lock. It is a bit of an eye sore, adding yet another fastener and component to a knife when it doesn’t need it, but the overtravel stop does solve a problem endemic to the form.
