Suehiro Cerax 404 Whetstone #320 (Thick Version)

by Suehiro


As a top pick for Ryky, the Cerax 320 offers something few other coarse / fixing whetstone offers - great feel.  Most 320 whetstones offer speed, but are not pleasurable to use. This whetstone, is fast cutting enough to bring dull knives back to life, but does not make the user feel like they are simply grinding away material. It strikes a good balance between cutting speed,  feedback, and speed of wear.
