Old knife repair

[sharpsteel]

I have quite a few old but serviceable and, in some cases, collectable knives that are lazy. They don't have that same SNAP that the young ones do. Some of these I acquired this way, others just seem sticky and some BreakFree helped those a bunch. In several cases the knife is virtually unused. It sat in a drawer or stash somewhere and everyhting about it is minty except there's no there there. It doesn't close completely or the lockup is imprecise so I've gotta "help" it.

So short of taking them completely apart and bending the springs or making new springs from scratch, what can I do to improve the "walk and talk" of these puppies. I've cleaned them up and lubed them which helped some but not enough.

Thanks in advance.
