Review: 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. ## Features - Made from hardened spring steel. - Rigid blade is 12" long, .040" thick and 1" wide - Rule is precision photo etched and black filled for long life and easy readability - Graduated with quick reading 1/8" and 1/16" increments on one side and 1/32" and 1/64" on the other - Brushed finish ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B071FZ1NT7 | | Brand Name | Taytools | | Color | Black | | Customer Reviews | 4.6 4.6 out of 5 stars (341) | | Global Trade Identification Number | 00791617734845 | | Item Dimensions L x W | 30.5L x 2.5W centimeters | | Manufacturer | Taylor Toolworks LLC | | Material Type | Alloy Steel | | Model | MRSAE-12 | | Part Number | MRSAE-12 | | Style Name | Compact | | UPC | 791617734845 | ## Product Details - **Brand:** Taytools - **Colour:** Black - **Material:** Alloy Steel - **Product dimensions:** 30.5L x 2.5W centimeters - **Style:** Compact ## Images ![30cm Rigid Machinist Rule Ruler Hardened Spring Steel 4R Graduations in 0.3cm , 0.2cm , 0.08cm and 0.04cm MRSAE-12 - Image 1](https://m.media-amazon.com/images/I/81DlYmrN+gL.jpg) ![30cm Rigid Machinist Rule Ruler Hardened Spring Steel 4R Graduations in 0.3cm , 0.2cm , 0.08cm and 0.04cm MRSAE-12 - Image 2](https://m.media-amazon.com/images/I/81BvEM0WAgL.jpg) ![30cm Rigid Machinist Rule Ruler Hardened Spring Steel 4R Graduations in 0.3cm , 0.2cm , 0.08cm and 0.04cm MRSAE-12 - Image 3](https://m.media-amazon.com/images/I/81Ibu-YQ5PL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by L***R on 6 January 2026* Well maxe ruler.
