I'm selling this because it's so sharp that I was afraid to use it, so I haven't used it much. It's a folding type, making it convenient for storage. Also, there are 3 boxes of replacement blades, with 10 blades per box. One box has been opened and has 9 blades remaining. That's a total of 29 blades. The blade that's already attached will be discarded since I used it.
