Zero isn't the end of the ruler
The markings of the ruler dont start at the end of the ruler. This means you cannot hold the end against somethings and measure it. The ruler doesn’t even start a simple distance from the end. It’s more than an 1/8” but less than 1/4”. For woodworking or metalworking this thing is useless. If i hadn’t gotten it as a gift i would return it. Now it will sit in my tool chest collecting dust. I ish i could give it less than 1 star

    I needed an 18" straight edge to check the relief on my guitar neck while I adjusted the action. I looked in several stores and was about to give up finding what I was looking for. Then I thought I would try Home Depot and I found exactly what I needed. The ruler was the right length and weight and allowed me to determine the relief on the neck was where I wanted it to be.

    A good sized ruler with multiple scales...good for the shop
    Sometimes my tape measure is not the right measuring tool - particularly for certain woodworking projects. A ruler works better. This 18-inch ruler is a good size for projects that require precision. I have found that 12-inch rulers are generally not long enough and anything plastic will either bend or get nicked and then quickly become useless. This ruler solves the problem. 1. The markings do not start at the end, so you are sure that the first inch of the ruler is a full inch, and not worn down or cut just a hair short 2. There are two sets of scales, plus metric: 1/16" on one side, 1/32" on the other and MM on both sides 3. Stiff, but still flexible The only thing to note is that this ruler is stiff, not rigid. It is slightly flexible even though it is made of stainless steel.

    Dual scales. Markings don't start at edge.
    HD Store SKU # 504309. The ruler markings start about 1/8" from the left end. On the front the top scale is in 32nds and the bottom scale is in millimeters that has stamped 10, 20, ... 450. On the back the top scale is in 16ths and the bottom is in millimeters. The only thing I'm worried about is if this "stainless" steel rulers can corrode. I'm using it for photo mats. It is made in India and inspected in the USA.

    Empire 18 in. Stiff Ruler
    Excellent quality ruler, exactly what I was looking for. However, in my view, the price should be several dollars less (it should cost in the neighborhood of $7.00 or $8.00).

    Nothing to really say. It measures 18 inches because its an 18 inch ruler. It's also metal and it is also stiff. Only complaint is that it does not make the fun "wobble wobble" noise when you bend it back and forth. I'd give it five stars but it doesn't make the fun noise which I was really hoping it would.
