Kai Seki Magoroku Whetstone Combo 1000/4000 Grit
The Seki Magoroku Whetstone Combo 1000/4000 Grit is a double-sided Japanese sharpening stone with a medium face and a fine face. One stone covers both sharpening and polishing.
Why Choose a Combination Stone?
The 1000 grit side restores sharpness on a dull blade. The 4000 grit side then refines and polishes the edge. These are the two most used grits, so one stone handles routine sharpening from start to finish.
Choosing the Right Grit
- Coarse (220 to 400 grit): Fast metal removal for chips, damage and reshaping.
- Medium (1000 to 2000 grit): Routine sharpening of a dull but undamaged blade.
- Fine (4000 to 8000 grit): Finishing and polishing to a mirror-like edge.
Features
- 1000/4000 Dual Grit – Medium side for sharpening, fine side for polishing.
- Storage Case – Keeps the stone protected between uses.
- Soaking Lid – Lid holds water for soaking the stone before sharpening.
- Non-Slip Base – Feet on the base keep the stone steady while sharpening.

- Keep the surface slightly wet while sharpening by adding a little water as needed.
Double Bevel Knives
- Hold the blade at about 15° to the stone.
- Move the blade toward and away from you with light pressure until a fine burr forms.
- Work along the full length of the edge.
- Sharpen both sides equally to keep the edge symmetrical.
Single Bevel Knives
- Sharpen the bevelled side first, using the angle recommended by the knife maker.
- Work with light pressure until a fine burr forms.
- Turn the knife over and sharpen the flat back with about one tenth as many strokes.
Remove the Burr
- Lay newspaper on a flat surface.
- Hold the knife at the same angle and draw the edge lightly across the paper, side to side.
