A cutting device has a selectively replaceable and reorientable blade. The cutting device includes a housing and a carriage that is movably disposed in the housing, the carriage being movable between a retracted position and an extended position. The cutting device also has a cutting member that is removably disposable and reorientable in the carriage and a cover member that is removably attachable to the housing. Further, the cutting device may include an adjustable blade depth assembly providing the ability to direct and/or pre-select the depth or length a blade disposed in the blade carriage will reach upon engagement of a dial component and/or switch member operably connected to the blade carriage.

A pocket knife includes a chassis that defines a cavity. A blade having a cutting edge has a retracted position in which the cutting edge is inside the cavity and a deployed position in which the cutting edge is outside of the cavity. A front operator inside the cavity engages with the blade to move the blade to the retracted position, and a rear operator inside the cavity engages with the blade to move the blade to the deployed position. A spring connected between the front operator and the rear operator provides a tension between the front and rear operators. An adjustable connection between the spring and the rear operator has a plurality of positions to adjust the tension between the front and rear operators.

A utility knife configured with a retractable cutting blade that is extended and retracted by a blade actuation mechanism. The blade actuation mechanism includes a blade trigger assembly and a blade carriage assembly that are operably connected in variety of configurations, including a configuration with a rack-and-pinion arrangement between the blade trigger assembly and the blade carriage assembly. The rack-and-pinion blade actuation mechanism is configured to automatically retract the cutting blade as the cutting blade is lifted from the cutting surface.

A landscaping dripper system tool that safely enables releasing drip irrigation feeder pipe from the barbs of connected fittings and end-point devices; emitters, sprayers, manifolds, etc. The tool includes a channel and a parallel, recessed knife blade that receives and cuts the irrigation tubing wall, releasing the feeder pipe from the connected barbed fitting. The knife blade tip extends into the channel to a depth based on a standard irrigation tubing wall thickness, so when the operator slides the tubing with attached barb along the channel, the tubing wall is safely cut.
