Used for about 3 months. Selling because I'm switching to a different brand. There's a little bit of dirt, but it doesn't affect usability. Also, there are 10 replacement blades, so it's a bit of a bargain. *I bought it once, but lost the body, so I repurchased it. It seems to be discontinued on Amazon, so it might be a little rare. If you like unique items, please consider it. KAI brand blade, scalpel blade, cutter with 5 replacement blades, made in Japan. Suitable for shoji screen replacement, paper cutting, and fishing gear.
