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).
- Sharpen Secateurs every couple of weeks
- Sharpen Shears and Topiary Clippers EVERY TIME you use them - the difference is amazing
