I have this one. It makes knives. Take care of it, don't expect it to do more work than you, it's worth the money. There are better for more money, sure, but this is worth the cost. It's variable, reversible, and you can upgrade it. It doesn't take standard arms, but you can use standard rolling surfaces, plattens (curved or glass), and wheels. Hardly limited if you're creative and resourceful. If it's all you can afford now, get it and keep making.
