This works great but I had to make a couple of attachments to hold the edge of the knife to how it more secure. Other than that reason it works great and can easily adjust the angle to suit your needs and design. Once adjusted you can lock into place so you can turn the blade around and get the same exact angle on the opposite side. Another thing I'm going to change on this is the turn buckle on this I will be making a wheel to slide over so that I can turn it by hand instead of having to use a wrench. I will also be adding a digital angle gauge to the back of the platten so I can see the exact angle I'm using. If i change all of this it will be awesome. I would imagine if these were added to this it would cost considerably more.
