Wooden shaft for NT Design Knife D-400P.
It is a design knife with a replaceable blade, and I think that many people use it for paper cutouts, eraser stamps, and various other crafts.
Compared to plastic, the wooden handle has a warmer feel to it, and it fits in the hand much like the handles of various tools that have been used since ancient times.
Also, the wood grain is different one by one. It will be your own special design knife.
