Review on Gages SQ CTR3 3 Centering Square by Victor Houser

Handy tool. Made in India and accurate enough to use an optical centerer on reticle marker lines. I also find it useful for laying a line at a 45 degree angle from an outside corner or the end of rectangular things. I think he can also serve as a ninja star. Some edges/corners were sharp enough, others weren't, and the fast rock pass made it easy to hold.
