This is a replacement blade for an FIA hair clipper. I've used it for about a year, and when the cutting performance declined, I sharpened it twice with a liquid-type sharpener. Compared to a new blade, the sound has become louder, so I'm offering it to someone who doesn't mind the sound and is willing to maintain it. I will ship it via Yu-packet Post Mini, so I will remove the blade from the package and wrap it in bubble wrap for shipping.
