I almost bought a Work Sharp flexible-belt sharpener last month, but opted for a more-traditional Spyderco Sharpmaker instead. I’m glad I didn’t pull the trigger (so to speak) on the base-model Work Sharp, because Darex has been working with Ken Onion to design a professional-grade version.
The new $150 Ken Onion Work Sharp includes all the grindy goodness of the standard ($70) Work Sharp shown in this video, but also features adjustable grinding angles, variable speeds, and wider abrasive belts. Basically, everything you need to put exactly the edge you want on your blades.
For those of us who’ll never afford Clay’s pricey Tormek Sharpening Systen, this might be the best automated sharpener out there.
