Second time I joined this drop. This time I ordered two but only one arrived. Massdrop did refund me after a few to and fro's, but seriously how can they stuff this up? It's their business.
Anyway, I like these as I use it mainly to keep my fishing and camping knives honed in between proper sharpening. The first one is in it's prime now as the diamond section has lost its harshness and now leaves a much smoother finish on the edge.
