Nice !
Did you cast the blank, Steve, or is it a AA acrylic (looks like) ?
I am thinking of doing some seam rippers, but I find the kits a bit expensive for what you get, and also the internal flat springs a bit questionable (these springs come into play when you insert the business end of the ripper in reverse).
I was wondering about avoiding the kits and just buying long-shaft seam rippers, shortening the shaft, and gluing into the blank. No protection for or from the sharp tip when the ripper is not in use.
Any thoughts ?
