Very accurate & easy
I did not want to spend the extra money on a Bloc Loc ruler. My HONEST opinion after using this to square up my HST's, it's money well spent! Other methods are out there, class them as good, better, or best. Bloc Loc is the BEST! The proof is in my photo, these blocks are not pressed nor sewn together, the points & intersections lines are perfect! The 6 1/2" will square multiple size triangles. Very pleased with this product.
