Most Niwaki tools are made from carbon steel. Although wonderfully strong and resilient, the metal will stain, rust and eventually lose its super sharp cutting edge without proper care. Looking after them is easy and will prolong their life no end. Here's how to do it:
- Japanese steel is hard and sharp, but it can be more brittle than some people are used to. It will dent and chip if abused. Hence, do not cut wire, metal, stone, plastic or any other hard material. Bamboo fibres and some very hard woods, especially those with knots and burrs, can damage sharp edges
- Cut diagonally across branches, not straight across
- Do not twist or apply uneven pressure, as this could damage the blades as well as your wrists and arms
- Pay attention to the maximum cut dimensions recommended. Use a pair of loppers or a pruning saw for more substantial branches
- Use the base of the blades (the parts nearest to the handles) for heavier cuts
- Never put tools away wet. Dry them with a cloth before retiring for the day
- Regularly remove leaf resin, rust and gunk with a Crean Mate (like a pencil eraser for plant sap). Dry, then wipe with camellia oil and store in a dry place
- 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 clipping box. Use a Niwaki sharpening stone 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, and you will notice the difference
Lastly, do put your own safety first and remember you are using a supremely sharp object. Always know where your cutting blades are relative to your body, and take no risks.
