Claims21
A blade sharpening device comprising:
- a support plate having a base and a raised feature that projects from the base;
- and
- at least one force applicator configured to apply force to a blade placed over the support plate and in contact with the raised feature, the at least one force applicator applying force to deflect a front edge of the blade comprising a cutting edge and an opposing back edge of the blade toward the base of the support plate, a gap being present between the front edge of the blade and a front upper surface of the base of the support plate.
A blade sharpening system comprising:
- a blade to be sharpened;
- a blade support plate in contact with the blade, the blade support plate having a raised feature having an upper surface that contacts the blade at a contact position on the upper surface, the blade being pre-tensioned over the contact position with a front and a back of the blade being deflected toward the support plate;
- and
- a sharpening surface for contacting a cutting edge of the blade.
A method of sharpening a blade, the method comprising:
- providing a blade to be sharpened attached to a support plate, the blade being pre-tensioned over a raised fulcrum comprised by the support plate, a front edge and a back edge of the blade being defected toward the support plate;
- holding the support plate and blade with a holder;
- and
- utilizing the holder, contacting the blade to a sharpening surface while the blade is held in a pre-tensioned configuration.
