Japanese razor, a remarkable achievement by Miki. I believe it's a double-edged type. Total length: 153mm, blade width: 21mm, blade length: 40mm, back thickness: 5mm, 40g. The body showed no signs of use, but there was some rotary tool work on the front hollow grind, which I corrected, leaving a little steel near the blade edge to avoid excessive thinning. This ensures it's suitable for future use. There are also some scratch marks on the back hollow grind, but they don't affect its use.
