Best sharpener I found for Montec Heads but wears out to quick. This is my third and last one if it wears out right away. People at Montec Outdoors used to try to resolve the problems but now they are down right rude if you complain about the longevity. My Pro Shop doesn't handle them any longer because they don't last but I'm giving them one more try.
It's a really nice sharprner. The only thing that bothered me was that the picture showed a leather sheath which Is why I ordered it but it came with a nylon sheath which will have half the life span of the leather one.
