Niwaki Twin Diamond File

More Information

Double sided diamond file for coarse sharpening and re-setting old blades. This is what we use when you send in battered old shears and secateurs with nicked and chipped blades - the #120 side eats through the steel to a new edge, then the #300 gives a crude finish before moving over to a whetstone to get a decent edge. Use dry. Indispensable.

Tips

Essential for fixing damaged blades, but also useful for sharpening rough edges like mower blades.

Caring For Your Tools

Most of our sharp tools are made from carbon steel - this means they may, through regular use, stain (and eventually rust) and gradually lose their edge. Caring for them involves three things…

1. Correct Use:

Japanese steel is hard and sharp, and can be more brittle than some people are used to - it will chip if abused
Do not cut wire, metal, stone, plastic or any other hard material (even bamboo fibres and some very hard woods, especially knots and burrs, can damage steel edges)
Do not twist or apply uneven pressure
Cut diagonally across branches (not straight across) so you cut along the fibres
Pay attention to our maximum cut dimensions, and don’t overdo it (shears are not loppers)
Use the base of the blades, not the tips, for heavier cuts

2. Keeping Them Clean:

Remove leaf resin, rust and gunk with a Clean Mate and water
Dry, wipe over with Camellia oil and store in a dry place

3. Keeping Them Sharp:

New tools won’t need sharpening for some time, but after a while you’ll notice them gradually lose their edge, especially if you’re box clipping (you need REALLY sharp blades to get a good finish with box). Use the Niwaki Sharpening Stones for best results (#1000 grit is best for general sharpening).
