A hand-held tool for carrying a scraping/stripping blade. The tool includes a base element, generally T-shaped in outline, including a handle and a blade receiver with a fixed jaw face oriented toward the central plane of the tool, and a lever aperture extending through the blade receiver adjacent to the handle. A locking aperture in formed in the handle remote from the blade receiver means, with a locking rail disposed therein, oriented generally parallel to the blade receiver. A blade clamp is pivotally attached to the base element and includes a movable jaw face and a perpendicular blade clamping lever, divided into three portions in a zig-zag pattern, carrying a latch, adapted to engage the locking rail at its extremity, and an unlocking point at its distal end. The blade clamp pivots on an axis at the base of the fixed jaw face and the clamping lever extends through the lever aperture and into the locking aperture. In the open position, force applied to the locking point urges the latch against the locking rail, causing the lever to flex and allowing the latch to engage the locking rail. Similarly, in the locked position, force applied to the unlocking point causes the lever to bend in the opposite direction, allowing the latch to disengage from the locking rail. This allows for quick blade insertion or blade reversal for convenient safe storage.
