Leatherman Ruler

Most Leatherman tools (except all but one of the Juice series and all of the Squirt series) feature a ruler as part of the body of the tool. The length of the ruler, therefore, depends on the size of the tool.

Due to the fact the ruler is part of the body of a folding tool, it isn't as accurate as a tape measure or yardstick, but will do in a pinch.

Some Victorinox Swiss Army knives contain a ruler as part of a screwdriver/ruler combo tool, and some contain a fish scaler which also functions as a ruler.

This implement is found on the following multi-tools:

Leatherman Blast
