Customer Reviews

Rated 1.0 out of 5 by 1 reviewer.
Rated 1.0 out of 5.0 by The item purchased was returned as defective I expected a reasonable quality machinists combination square for $132. The rule was of the quality I expected. The three cast parts were not. The castings were rough, the machining was rough with some hanging burrs, the paint quality was poor and was chipped off in many places with rust underneath. The scribe knob came off with the scribe stuck in the square and the level in the square was not mounted parallel to the machined face of the square giving erroneous level indications. August 6, 2013
