## Customer Reviews

### ⭐⭐⭐⭐⭐ Perfect thin, flexible, and easy to read ruler
*by B***H on July 23, 2016*

I was looking for a 12" thin and flexible steel ruler with clear easy to read markings. Key for me was thin and flexible - I'd purchased a few other rulers and they were all thicker and mostly rigid. This ruler is perfect for my work. The graduations are fantastic for measuring to precise lengths and I've found the need to purchase another as I'm always wanting to use this in lieu of my other shop rulers. One item to note is that this ruler is only 1/2" wide - I personally like it being thinner but it is not your "standard" width.

### ⭐⭐⭐⭐⭐ The Machinist's Ruler
*by M***L on October 4, 2015*

Excellent for machine work. High contrast allows easy read against bright, reflective metal backgrounds (aluminum, stainless, etc.) and under bright shop lighting conditions. Graduation in tenths is extremely practical for checking work while it's on the machine table or for laying out work. Couldn't ask for a better shop ruler.

### ⭐⭐⭐⭐⭐ Excellent Ruler.
*by G***Y on October 3, 2021*

I thought there was only a 6 inch version of this ruler, but now I know there's 12 inch version too. And I can measure in hundredths up to a foot.
