I found that a nice 4" double square is a pleasure to use, and very handy.
They usually go for $40, but I've seen sales for $20.

I use that more than a fixed engineering square.


If you wish to check that your TS blade is vertical, for instance, do you
just use the base of the double square?


I move the blade so that it's flush with the handle, so it has the
same shape as an engineering square.

It's also handy to measure router bit height, etc.
