If you are fortunate enough to own Work Sharp's Ken Onion Edition MK.2 knife and tool sharpener, you're going to want this attachment. (And if you don't have the MK2 yet, you might want to take another look!) The grinder is designed to mirror the systems used by professional blade makers, but you get high-quality, precision blade maintenance at a fraction of the cost of professional equipment. It attaches easily without the need for tools, and it features a simple hand-operated system for changing belts. The now larger abrasive belts are available in various grits that are adjustable from 10° to 35° with three convex edge profile settings, and the belt speed can also be varied to suit your different sharpening needs to perfection. Basically, being able to modify your blade has never been so affordable or so enjoyable. Snag yours today! Requires but does not include the Work Sharp Knife & Tool Sharpener (sold separately). You can also buy the two together as a knife-sharpening system set.
