So, I recently purchased a Spyderco fixed blade and stupidly tried to reposition the pocket clip on the sheath while distracted. One of the small rubberized plastic spacers squirted away from me, and is now gone forever... Can anyone tell me the exact dimensions of the part, so I can go buy a replacement at a hardware store? I know Spyderco would replace it, but I don't want to wait. Thanks!
