摘要

An aluminum ruler (21) has a pair of straight measuring edges (24) with imperial and/or metric scales, and an inner pair of retaining tracks slidably supporting a one-piece plastic molded combined sliding handgrip and braking device (31). The sliding handgrip is shaped and dimensioned so as to be comfortably held in the user's loosely clenched fist to slidably displace along the ruler to the user's desired position.
