Thread: What coticule to buy for a smooth edge?

The first is one of my favorite finishers and the other coticule I was not personally a fan of. Although some coticules can have weird looking surfaces and be great finishers while others can have plain surfaces and not be great finishers. I would say magnese is usually a good sign but again it depends. Natural stones can be hit or miss, I wish coticule vendors would have some sort of grit rating for coticules. Like having extra extra fine/ extra fine/ fine instead of just "its a coticule they are all 6k-8k range and they all are great finishers." I could shave with 6k or 8k synth stone edge but I don't want to go buy from a synth stone vendor that says "yea my synth stones are 6k-8k with some being 10k+ but they are all good stones for whatever you are using it for. Trust me satisfaction GUARANTEED...but no returns accepted." sort of bad example but w/e, I suggest buying coticule from someone that offers return. GL

What vein is the 2nd one? I typically avoid cotis with that color and surface pattern like a wood grain as they typically are not pure coticule but mostly a mixture of other sediments and minerals that do no cutting or refining of the edge and much less "coticule."
