Well once you did that thumb nail thing it may have dulled it some. Probably did IMO. So if I was the seller I wouldn't feel obligated. to hone it again at no charge but you could ask him or send it to someone else who hones for other people. BTW, just because it won't 'pop' hair doesn't mean it won't shave if the TPT feels good. Will it shave hair on you arm easily touching the skin ? If it won't do that it sure won't shave your face.
