Niwaki's sharpening stones are designed for secateurs, but are also great for shears, clippers and other blades. The concave edge follows the curve of the blade perfectly, and they’re small enough to get into tight spots.
The #220 is a course stone, for rough blades.
See use instructions below, but the golden rule is to soak thoroughly each time before use. And not to drop them.
Made by: Niwaki
Made in: Osaka, Japan
Specifications: 5 1/4" x 3/4" x 1 1/8"
Soak stones in water for a few minutes before use, and keep wet during use
FOR SECATEURS: Use the concave edge of the stone, moving from the pivot towards the tip of the blade, following the curve as you go
FOR STRAIGHT BLADED SHEARS: use the flat side of the stone
Move back and forth along the whole length of the blade
Use as much of the stone as possible, not just the top inch
This is a gentle action - don’t use too much pressure
Next, turn the secateurs over, and use the flat side of the stone to smooth the burr off the inside of the blade, going slightly over, creating a very fine bevel
Use the convex edge of the stone to clean off the curved edge of the bypass
Finally, clean and dry the secateurs, and wipe with Camellia Oil
