The simplest way how to estimate an edge angle are measuring grooves. They work if the bevel is not too short.
Professional tool is a Vernier protractor.
Catra laser goniometer enables to measure bevel angles, while the two previous tools measure only the included (edge) angle. Catra tells us if the blade was shaped symmetrically.
