I've been using a Gesshin 400 for a while now and I've always though of it as a Beston that wears a little faster, gives a little nicer finish and feels great. HOWEVER, I recently did some work on a couple of very wear-resistant blades (A-type and Niolox) and I could swear the G400 is significantly faster than the Beston. Anyone else have this experience or am I just imagining things?
