Excellent quality ruler!

### ⭐⭐⭐⭐⭐ Review
*by K***D on 1 November 2020*

I ordered this rule to replace the Office Depot metal ruler I've been using for years. On first examination it is plain that this is a serious tool. I was immediately impressed by the sharpness and readability of the scribed markings. The first thing I did, though, was put it side by side with my Starrett combination square and found it is absolutely spot-on accurate. The measurements appear in four different scales, one on each edge and they appear as eights, sixteenths, 32nds, and 64ths. This is different than on other rules and does require some adjustment on the part of the user. Measurements begin at the end of the rule so there is no "dead spot" to account for. Other reviewers have suggested it should have a hanging hole, and I agree, but I also own a drill press, so ... :-) I like this rule well enough that I ordered the 6" model to keep in the chest pocket of my shop apron.
