Wizard Industries crams a few tools you use all the time — a straight edge, marking gauge, ruler, level, and compass — into one tool to make their Measure Level. With this 8.7oz tool you can measure, transfer measurements, mark straight lines, find level, and create circles and curves.
The Measure Level consists of a 24″ aluminum ruler, marked in both inches and metric, and three aluminum blocks. Two blocks sport stainless steel points on the back for marking, and the third houses horizontal and vertical bubble vials for finding plumb and level. The blocks slide along the ruler and lock into place with brass thumbscrews.
You can find the Measure Level on sale at Amazon for $20.
