Latest Patents

One of her latest inventions is the hand tool edge tester. This device is designed to evaluate the sharpness and smoothness of the cutting edge of blades used in hand tools, such as knives. The invention features a mechanism where the knife blade is held stationary along a horizontal axis. A long piece of solid tape, made from cuttable substrate material like Teflon, moves within a reel-to-reel tape mechanism. This mechanism allows the tape to travel horizontally while also moving along an upwardly inclined, diagonal pathway. As the blade slices through the tape, a load cell measures the cutting force exerted against the blade. This setup provides a more accurate measurement of the blade's performance, yielding a cutting profile that indicates the relative sharpness and smoothness of the cutting edge.
