Keep your Shun blades in razor-sharp condition with the Shun Combination Whetstone. This Shun Combination Whetstone offers you two grits: a fine 1000-grit side and an even finer 6000-grit side. This whetstone is a good choice for sharpening your Shuns when they’re not very dull.
The 1000-grit side lets you put a keen edge on your Shun, then polish it to perfection with the 6000-grit side. You will need to soak this whetstone before sharpening thoroughly. Try the Shun 400/1000-grit whetstone if your knife is exceptionally dull.
