I do shave with one. In fact, I own and shave with 4 different razors. There's a little test one can do to see if the razor is sharp enough to try to shave with. It's called the 'Hanging Hair Test'. (if it will shave your arm, it may not shave your beard). To do the hanging hair test, pull one hair from your head. Place the razor, back down, blade up on the counter. Holding the hair in one hand only, bring the hair down to the blade. (having someone or something hold the blade and gripping the hair on both ends is cheating). Hold the hair in one hand only and bring the hair down to the blade. If the blade is sharp enough to cut the hair when the hair touches the blade, it passes the hanging hair test and is sharp enough to try to shave with. With my gray hairs, I usually need my razors to be sharper than that.
It's a lot different from sharpening a hunter enough to gut a deer!
The razor looks nice, though. Good luck sharpening it.
