This 400 Grit sharpening stone will fit the Zwilling sink bridge for the easiest stone sharpening event.

This stone is great for sharpening. For a really thorough sharpening, you need to use stones from low grit and work incrementally up to higher grits in order to produce that perfectly razor-sharp mirror-finished edge. This grit is great for transitioning between a lower grit of say 250 up to 1000, to scalpel-like edge. As with most stone sharpeners, there is a bit of a learning curve but can easily become one of your favorite maintenance activities. I suggest practicing on a cheaper knife first when you are just getting the feel for stone sharpening. However, properly using whetstones is totally worth the time and money for that perfectly clean cut. It just elevates the entire cooking experience.

I use the 400 grit with the Bob Kramer sink bridge. The 400 grit is rougher and is good for repairing or putting a new edge on the knife. Follow it up with a finer grit for polishing.
