Am I right? I mean, am I right? They really do have screws. And the screws are used to tighten them, just like the screws in “normal” vises. So, why are they called “screwless”?
If they were closed by a cam or a wedge, or some other mechanism; I could understand calling them screwless. But they are closed by a – wait for it – by a screw. Yes, A SCREW. A REAL SCREW that works like all other screws.
I know that these screws are somewhat hidden from view. All you can usually see is the head. But that counts. Doesn’t it? And even if it didn't count, the screw is still there and it still is the basis of the closing mechanism.
Inquiring minds want to know. I want to know.
