Thread: Looking for info on a speckled Coti

La grise can have big bright orange spots on the surface but I can not say yours is one because it is an old mined coticule. Coticules mined decades ago can not be ID'd because the names are long lost.

Old coticules selected for razors had a certain combination of hardness vs softness vs garnet content, which is why some of us prefer older coticules labeled for razor use.

For example harder coticules may have less garnet per square inch than softer coticules thus making them more suitable for tools and knives. If you asked Maurice today for a coticule for razors he would pick one based on a degree of hardness vs softeness for razors.

Hard coticules- less garnet per square inch but agressive cutting power.
Softer coticules- more garnet per square inch, finer polishing ability but not much cutting speed.
Perfect balance of those two is what you want for razors and older mined coticules were sold for razors after being tested for that purpose.
