While the function of the T-Bevel is unmistakable, the fit and shape is not what I expect from Shinwa tools. The body of the tool is machined on a belt sander and is not very flat. The blade is wider than the body and not centered in its slot. Its end radius makes the corner stick out at certain settings. The blade pivot is smaller than the slot for smooth movement. The design is pretty nice with the end clip but I'm disappointed with the overall end result. If you get what I mean, that's just plain wrong.
