A tool for steeling a knife includes a frame and first and second steeling components. Each of the components is shiftably mounted relative to the frame for movement between a first position and a second position. The steeling components cooperatively define a knife interface configured to engage and thereby steel the knife. The steeling components are resiliently biased into the first position, with the knife interface moving as the steeling components shift between the first and second positions.

A controller is provided for use in controlling a blade sharpening system that includes at least one grinding wheel operable to sharpen the blade. The controller includes a memory device, and a processor communicatively coupled to the memory device. The processor is configured to receive signals from at least one sensor, the at least one sensor operable to monitor rotation of the at least one grinding wheel. The processor is further configured to adjust a position of the at least one grinding wheel relative to the blade based on the received signals.

There is provided a base-integrated blade manufacturing method for manufacturing a base-integrated blade by fixing a cutting blade having a circular opening to a base having an annular projection. The method includes a first step of preparing the base having the projection that has an outside diameter greater than a diameter of the opening of the cutting blade, and the cutting blade, a second step of lowering a temperature of the base and thus shrinking the base to have the outside diameter of the projection smaller than the diameter of the opening of the cutting blade, a third step of inserting the projection into the opening of the cutting blade, and a fourth step of raising the temperature of the base and thus expanding the base in such a manner that the cutting blade is fixed to the base.

The pizza cutter cleaning, storage, and isolation device 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.

Dynamic regulation of contact pressures in a blade sharpening system is provided. An example multiphase grinding wheel has a grinding face with one or more abrasive concentric rings for sharpening the cutting blade of the log saw machine, and one or more padded concentric rings consisting of fiber padding. Sharpening with the multiphase grinding wheel improves cut quality, increases blade life, removes glues and varnishes from the cutting blade, reduces blade deformation, and hones the edge of the cutting blade. A pneumatic tensioning system uses air bladders to apply dynamic cushioning and processor-controlled contact pressure between the grinding wheels and the cutting blade during sharpening. The fiber-padded grinding wheels and the air bladder tensioner provide improved sharpness of the cutting blade and longer life for the mechanical components.
