A lockable tool with a sliding scale release is formed with a frame and a tool coupled to the frame with a locking mechanism to lock the tool into an extended or retracted configuration. A release mechanism is attached a scale on the side of the frame. The scale is coupled to the frame. The tool is constructed such that sliding the scale along a longitudinal axis of the frame automatically unlocks the tool from the extended or retracted configurations. The tool can open and/or close automatically. The tool, such as a knife, can swing open or extend out a front opening in the frame.

The pizza cutter cleaning, storage, and isolation device disclosed herein may allow a user to store and clean pizza cutters between uses, while also isolating each pizza cutter intended for specific consumers. Such a device may implement a cartridge system, one or more of which may be installed in a main body, into which a single pizza cutter may be placed. The cartridge may be designed to isolate and clean the pizza cutter installed therein, and the pizza cutters themselves may be color-coded, or the cartridges may be color-coded, so as to prevent cross-contamination of the cutters, the pizzas, or the debris picked up when cutting a pizza. The cartridges may further implement a sanitizing bath into which a pizza cutter head may be suspended, or may implement a catch tank for waste debris. The device may further comprise a blade sharpener for additional functionality.

A knife block system for holding and sharpening knives includes a knife block and a knife sharpener assembly. The knife block has a housing and defines a plurality of slots for receiving the knives. The knife sharpener assembly is operatively associated with the housing, and movable relative to the housing, between a closed configuration within the housing and an open configuration extending out of the housing. In the closed configuration, the knife sharpener assembly is fully nested within the housing of the knife block and hidden from view. In the open configuration, the knife sharpener assembly is accessible by a user to sharpen the knives.
