I bought a different, less expensive knife grinding jig that I thought would fit my needs.... I was wrong.I'm a somewhat new knife maker, but I e been at it enough to know what I need, and what works and what doesn't. The previous jig I had was not "true" and had a bent level set screw, right milled pieces, and was just all over unfinished mostly.This particular jig from vevor is absolutely amazing, both by comparison to the other, but also all on it's own. If I would have purchased this before, I would never have needed anything else.Every little piece is quality, and perfectly aligned.The screws fit perfectly in all the pre tapped holes, the slide pieces are pwdt fit and slide, and so exactly what is expected of them.The bevel adjustment / set bolt / bar is precise, and moves in increments that allow for fine adjustment without any hassle. The threads are smooth, yet right enough to set by hand, but also stay out of you don't lock it down with the finger screw / adjustment "set screw".I am not kidding when I say just using this jig makes my knife making improved to the point of pro level with the grinds I can produce now .I will update this post with pictures soon once I get them all ready for upload. I should.hav3 waited to post, but I couldn't wait as I needed tomout the word out. I almost passed this item by as the lack of reviews and info, so I wanted to post it now, that's how amazing this jig is!TL:DR: if you need a knife grinding jig, and aren't sure, you cannot go wrong with this one, everything is perfect!
