Thread: Why a Wedge Spacer?

I swear I've searched but can't find out why a wedge shaped spacer. Is a wedge necessary?
I plan on rescaling my DA and would like to know the "why" of things before attempting them.

Thanks!

Short answer:
It allows there to be a < 1/8" space at the toe of the scales and a 1/4" space at the pivot without bowing the scales and causing undue stresses.

I think that a flat spacer warps a lot of scales and causes stress in the center portion. Hard to explain why, but if the pivot end of the scales needs to be forced out to pin together, then the center portion of the scales get forced inward. It also solves a lot of problems with blades not closing centered, etc. Besides all that, it looks better and is harder to do well.

But why can't you just make the spacer the same thickness as the spine of the razor, so that the scales are the same distance apart at both pins?

If I understand your question, take note that tangs are tapered in width being narrower toward the tail than toward the spine, so as it rotates it will bend any scales that are not bowed to allow for the razor to swivel open

Gotcha. So, ideally would the scales be flat when the blade's fully extended, and bowed when the blade's fully closed? In other words, make the wedge match the taper of the tang.
