Miki Giken Highest Quality Stone Tool Koyasuke (Chisel) - 50mm, No Blade This item has been stored for a long time. The bag is a little dirty, but it's unopened and the Koyasuke itself is in beautiful condition with no rust. Hammer head only. Included: Box, Instruction manual (Please consider these as extras due to their age). I'm not particularly trying to sell this, and I'm considering using it myself if it doesn't sell. Please understand that excessive price reductions are not possible.
