This Japanese Professional Sharpening Whetstone, (1000 grit) will give a razor sharp edge with a mirror like polish.
It is made for professional use. It sharpens very quickly especially with high-carbon steel blade with a much cleaner scratch pattern but holds its flat surface much longer than other coarse grit stone on the market.
It is shipped in a wooden storage case that can be used as a stone holder while sharpening. The case has rubber feet to help prevent slippage.
