Complete sharpening kit

The Iwatani 9-piece set includes two double-sided whetstones covering 400/1000 and 3000/8000 grit, a bamboo base with rubber feet, a silicon holder, a leather strop, a flattening stone and an angle guide. White corundum construction provides corrosion and heat resistance for long life. Water-only sharpening keeps the process simple and economical.

Home cooks and professionals

This kit suits anyone who wants a single system to repair damaged edges, sharpen dull blades and finish with a polished razor edge. The angle guide helps beginners maintain consistency while the non-slip base improves safety. Buyers who only need occasional touch-ups or prefer electric sharpeners may find the full stone progression unnecessary.

Four-stage grit progression

The 400 grit removes chips and reshapes bevels, the 1000 grit restores a keen edge on moderately dull knives, the 3000 grit removes burrs and the 8000 grit delivers a mirror polish. The flattening stone keeps each whetstone surface true. Stones measure 17.78 cm by 5.99 cm by 2.95 cm, so very large blades may require multiple passes.

Questions about this item

Does the set include a base so I can use the stones on my countertop without slipping?

Yes, a bamboo base with a rubber backing and a silicone holder are supplied to keep the whetstones stable during use.

Can I use the 400 grit side to repair a chipped chef's knife and the 8000 grit side to polish it afterward?

The 400 grit side is intended for repairing chipped edges and the 8000 grit side for final polishing, so the set covers both steps.

How do I know I am holding the knife at the correct angle while sharpening?

An angle guide is included in the 9-piece set to help maintain a consistent angle on every stroke.
