greetings all,
had to ask this as maybe somebody knows. how come some of my enduras/delicas lock up like a vault and others have some up and down blade play? not only spyderco's but have had others do the same. i realize when you grip them just right, the lock can depress slightly. the spyderco dent helps immensely. just wondering if any body had any suggestions for a fix. best regards to all and thanks.

Well maybe some of the other ones have worse tolerances. A lockback works because the blade tang has a slot where the lock fits into. If there were loose spaces within the tang, that would mean the blade could rock back and forth. And when you squeeze, it's possible that the lock is moving up, and giving the blade space to move back and forth.

What do you define as up and down blade play?
Reason: The FRN handled knives have a bit of gap between the steel liners/FRN and the screws in order for the screws to fit. If these tolerances are kept very high then there is no movement of the parts, that can be called "blade play", however, tighter tolerances mean more time, time=money.
This slight upward movement of the backlock is considered normal by many.
There has been advances however. The tri-ad lock and this:

For me some do and some don't. Sharpness seems to minimise it as cuts are lower pressure. Also tighter pivots *seem* less prone to this.

A very slight vertical play in lockbacks is fairly common if they are engineered for strength.

As you've noticed, slight vertical play is common but not universal in Spyderco midlocks. In my experience, if a given knife has it, there's really no way to eliminate it. You can accept it and live with it. You can do as a Randall collector suggested those wanting perfect knives do - buy six, cherry pick the best, then sell the rest. You can stick to the models that, so far, seem to be less prone to it - the Chaparral, Native V, and Sage IV. If none of those appeal to you, then you can move to a different lock, which may very well be blessed with a different but equally frustrating quirk.

greetings,
as always, great advice from the forum members. thanks zenith, on pointing out the liner/handle relationship. never thought about it affecting the lock-up. makes total sense. things shifting around. blerv and cheddarnut also mentioned the pivot screw. tightening does help. again, thanks guys for your input. best regards to all.
