Razor Miter

My students do lots of projects with balsa wood, and I was finding Xacto Knives to be lacking, so I went looking for a solution. Some sites offer products like this for an unreasonable price, and I saw the thing uploaded by Simonarri. I liked his, but wanted a few features his didn't have, as well as to use some of the fasteners I already had.

While I did not use any element of Simonarri's design, the idea and some of the dimensions were from his.

It uses one bolt #8 x 1.5 inches, Four #8 washers, one #8 nut, two M3 x 0.5cm screws (to hold in the blade) and one utility blade. I know it is an odd assortment of metric and american, but its what I had on hand.
