It looks like the brand name Master. A new production, not vintage. Not the highest quality. I'm going only by how it LOOKS in the photos. Perhaps the Master brand has copied this design?

You find them time to time at flea markets and such with people that sell $5 knives.

But, the Master brand has it written on there, from what I have seen.

So, not saying that's what you have...just it looks like those that I have seen. But that's neither here nor there....

When it's 5 am and I'm posting I say random things that are irrelevant. For sure send this to a honemeister and have them evaluate and put a good edge on it for you. If it is a razor or metal that won't hold up, they will tell you that.
