Review: A fabulous ruler! Great for using with rotary cutter or craft blades and keeping fingers safe!! - I have several types rulers of which I use for my sewing and crafting. What I didn’t have was a ruler that I trusted myself using when cutting with a sharp blade...with the triangle ruler I knew it would not only provide a straight edge for my pencil lines but also a way of protecting my fingers when using a blade! I can safely hold the top edge of one side of the ruler whilst using one of the others as the line for cutting or lone drawing. It has a variety of measurements on each side and all very useful. Perfect for my sewing pattern cuttings as when use my acrylic rulers, the blade catches and dinks the acrylic and makes my rotary cutter skip parts of the fabric leaving it attached, with this metal ruler, the blade (including craft knives) just skims past without obstructing the blade and the bonus of keeping your fingers attached to your hand! Very useful and a great price too. Definitely recommended!
Review: Well Built, Strong and Accurate - Needed a heavy duty metal ruler to be used a guide for a stanley or craft knife when cutting leather and other stuff and this ruler fits the bill perfectly an affordable price. Not really much else I can say about a ruler... the markings are clear and easy to read and comes in both imperial and metric and is the standard 30cm length. Being metal it's strong and robust feeling and I see no reason why it wouldn't last the rest of my lifetime. At the price paid I am happy that I got good value for money and would happily buy again if need be.

### ⭐⭐⭐⭐⭐ Well Built, Strong and Accurate
*by T***R on 22 July 2017*

Needed a heavy duty metal ruler to be used a guide for a stanley or craft knife when cutting leather and other stuff and this ruler fits the bill perfectly an affordable price. Not really much else I can say about a ruler... the markings are clear and easy to read and comes in both imperial and metric and is the standard 30cm length.

### ⭐⭐⭐⭐ Really well made, but no scale for inches?
*by R***X on 26 October 2020*

It has a bunch of different scales except inches... why? You'd think being one of the most common units they'd put it somewhere on it. It does have centimetres and other 100 base units. Really well made, sturdy, not too heavy. Recommended.
