"Bought this combination square, didn't expect much at this price. I was wrong, ruler on top slides smoothly & holds firm when clamped with screw. No wibble no wobble. Construction is all metal.
Tested for squareness by placing square on factory finished flat edge of MDF. Drawing line full length of exposed ruler (10") Then flipped square through 180 degrees horizontally, drew line again. No gap or crossover between first & second line. Proved square was dead accurate. repeated test three times same result.
Reading through reviews this square out performs the rest, not my words read other reviews.
Have used this combination square a lot recently & find it excellent. So my review will probably go with all the others that rave about this square."
