4EVERHOPE 12Inch Aluminum Alloy Triangle Ruler Measuring Tool for Engineer Carpenter (Metric System)

I thought it was cm on one side and inches in the other but it comes with a conversion table.Apart from that is very sturdy and big. Good value

I love this ruler for its accuracy, the standard test for this is to draw two parallel lines from a straight edge with the ruler facing left and then right. I did this and the two lines are 100% parallel. My woodworking is now mm perfect after using it.Only drawback and its a small one, the 90 degree edge is slightly grooved, this does not impact the draw line but it does chew through pencils.

Great tool. Excellent size to run your skilly up beside for quick square cutting on all size timbers.

Very good quality, extremely sturdy. It also gives the most common angles used. My only concern is will the markings on the tool ware off after time on the job, but otherwise very satisfied

A brilliant bit of kit that is both accurate and square. Superb quality and very competitively priced. A must for every handyman 's bench or toolbox. Highly recommended

A brilliant tool which is perfectly square. The bigger size has now made my Swanson square redundant.

Really good quality, strong, well made and good value. Used it to help mark and assist cuts through sleepers, by using it to guide circular saw in a perfectly straight line.

It was a present for my son-in- law.
