This is a old movie projector lens that I use for inspecting the edges of my tools. You can also use a camera lens for the same thing. I got mine at goodwill. These are fairly powerful (maybe 12X)and high quality. You do have to get close to your work for them to focus. I like this better than my 30 dollar hand lens.
