This month Kreg made its Multi-Mark multi-tool available for sale. It joins a long line of measuring multi-tools of dubious value like the Level Best2, the Squangle, and the Multiscribe Pro to name a few.
The tool appears to have two parts — a plastic handle with an embedded bubble vial and a slotted metal blade marked in increments of 1/16″ inches and apparently in Metric. The blade attaches to one of two points on the handle with a brass thumbscrew. Around one of the attachment points there are notches to keep the blade perpendicular to the handle. The blade evidently can also ride in a recess, keeping it parallel to the handle and 3/16″ away from at least one edge of the handle.
You can use the tool as a depth gauge, square, level and ruler, but some more advanced uses would be to layout mitered corners, set 3/16″ reveals, and transfer measurements.
The Multi-Mark retails for $20, but you can find it for as little as $16.
