Pros: Durability, Ease of Use, Effectiveness, Overall Quality
Simply the best.
My wife recently purchased me a whole new sharpening suite from Knife Center for my birthday. My previous set was used almost daily sharpening woodworking tools for my crew of 12 guys, plus cutlery for a whole slew of folks including professional chefs. Word gets around! I got 25 years out of my first set of DMT stones. You will not be disappointed.
