sharper image couldn't do better
Having signed up for a scenery painting class, one of these was required to do scaled reproductions. I've never used one before but found the look of this to be high quality. My instinct was right. This heavy, aluminum ruler is easy to read, feels nice in the hand and stands up to a bit of wear. Highly recommended for practical use.

Nice solid tool for the price.
All of my scaled rulers were chipped up and warped, so I thought I'd splurge on an aluminum ruler. This little guy is pretty accurate and the aluminum and will resist chipping unlike the wood or plastic ones I already have. One of the nicer things that I've noticed about this is that the center groove on each side is color coded so I can work visually rather than picking it up and flipping it around for the proper scale. In this case, I work in 3/8" and 3/4" scale a lot, so I am always looking for the blue stripe. Perhaps this is common on newer scale measuring sticks, but it is new to me as an adept amateur, so it is really delightful in a kind of common way. I'm concerned that the printing on the ruler may wear fast, it is fine so far with only a couple months of use, but the marks are printed and stand proud of the surface, not engraved. This is going to fail and wear away at some point, but so far so good.

Great tool for blueprints, but the coloring is only a sticker that peals off
This is a heavy duty item. I purchased both the engineer's and architect's scale rulers. They are solid aluminum and easy to read. The only problem I had was the colors marking which side you're using peals off. It is a vinyl sticker and does not stick to the metal that well.

Excellent Quality
Excellent solid aluminum quality product at a good price. As a bonus, could clearly be an effective self defense tool with the corners as sharp as a knife point. Clearly, NOT for children.
