Starret quality is great and the tool will hold some resale value,
but for woodworking you don’t need a fine square like that.

A cheap combo square can be tuned square easily enough with
a little filing. Starret squares are machinest tools – and overkill
for woodworking.

Not to dissuade you.

I’ve found the little 4” pocket squares very useful in setting up
joints and I also like the Veritas Cabinetmaker’s square. Veritas
makes a bunch of little specialized layout tools and I’ve found
them to be real time savers.
