CBN Benchstone - Spyderco, Inc. Spyderco is shortly planning to release their CBN bench stone. It will be 3" x 8" and dual-sided, with 400-mesh grit on one side, 800-mesh on the other. This stone will not come cheap, preliminary listings I'm seeing on retailers who support this forum, as here, are running around $92. I'm interested in most things Spyderco releases, and will most definitely try one of these eventually. This stone, with 2 useful grits one coarse and one fine, has the potential to become a primary stone in someone's sharpening toolbox. I'm currently using Spyderco's "Doublestuff 2" cbn field stone (which I've written favorable reviews for here at BF), and also their triangle cbn stones for Sharpmaker, which I just got a couple weeks ago and am still evaluating but initial impressions are very good. Spyderco is definitely starting to figure out CBN and that's great news for the sharpening community.
