WUSTHOF Sharpening Stone Whetstone
The Wusthof Whetstone consist of a combination of different high-quality, abrasive grits. The stone has two sides – one with a fine grit and one coarse. The coarse side is used to smooth off any unevenness while the finer grit is used to hone and sharpen your knife.
The 1000/4000 includes a non-slip holder.*
How to choose your grit: A lower grit number is best to repair a dull knife and fix minor chips etc. A higher grit number is better to refine an edge as your last step or to use as your day to day polishing.
