The sliding bevel is a useful tool when you need to get a different angle from 90°, being the blade full adjustable. A pivot screw allows you to lock the blade in place. It can be screwed directly into a thread cut into the brass side metal plate, or be provided with a wing nut.Another possibility, in my opinion the best, is when, instead of the wing nut, there is a lever with a threaded hole, very convenient and easy to operate with a simple thumb movement. One of my two squares adopted the screw tightening system without blocking nut and needs a screwdriver for tightening and loosening.
So it was easy to change the system and I had the opportunity for replacing the steel screw with brass fittings, a metal which contrasts nicely with the mahogany wood.
