- Polish the edge with a leather strop and 16000-20000 grit diamond paste
Some Detailed Recommendations and Tips For You
Firstly, the steel is expensive Japanese VG10 which means that it will hold an edge for much longer than regular knives however it will still require maintenance to keep it razor sharp. It's best to ALWAYS cut on wood or plastic surfaces and cutting boards and AVOID cutting on plates, marble benches or metal sinks as these will definitely damage the edge at at a microscopic level.
How the knife is maintained and sharpened depends on the sharpening skills of the person sharpening the knife AND the state of the edge. If you have whetstone sharpening skills then the following instructions will give excellent results. If not, we recommend using a professional sharpening service in your local area. Be careful not to inadvertently scratch the blade surface, bolster or handle when sharpening as this will take away from the visual beauty of the knife.
- If the edge has been damaged, pitted, or badly blunted - 1st 1000 grit to repair the edge followed by 3000 grit and then 8000 grit whetstone. Finally strop, the edge using a leather strop and 0.5 micron diamond spray/paste.
- If the edge is in good condition and slightly blunt - 1st 3000 grit followed the 8000 grit whetstone and then finally strop the edge using a leather strop and 0.5 micron diamond spray/paste.
- If the edge is in excellent condition and you just want to restore the razor sharpness then use a high quality steel followed by 0.5 micron diamond spray/paste..
