  • Patent number: 11426021
    Abstract: Provided is an apparatus which simplifies the removal of an onion skin comprising a skin contacting side (1), a cutting and spreading element (2), and a lifting member (31, 32). After the cutting tip (22) of the cutting and spreading element (2) cuts into the outermost onion layer(s) at a top end of the onion and slides downwards along an outer contour of the onion towards a bottom end of the onion to create a cut along the contour of the onion, the lower lifting edge (312, 322) of the lifting member (31, 32) slots behind an inner edge of the cut outermost onion layer(s) and the lifting member (31, 32) lifts up portions of the onion layer(s) in contact therewith as it slides downwards until it passes through the bottom end of the onion, thereby allowing a user to split apart the lifted portions along the cut to remove the outermost onion layer(s) together with outer hard skin of the entire onion in one go.

  • Patent number: 11305445
    Abstract: A surface texturing apparatus is disclosed comprising an actuated tool holder, at least two independent actuators, a cutting tool, and a guide for positioning an article in relation to the apparatus. A method of replicating a circular saw milled texture in the surface of the article is further disclosed. A first actuator draws the cutting tool across the surface of the article along an arcuate path having a predetermined effective radius, carving a groove into the surface of the article which replicates a circular saw milling mark of a circular saw blade having the predetermined effective radius. A second actuator modulates distance between or overlap of the cutting tool and the surface. As the article is advanced along the surface texturing apparatus, a plurality of replicated circular saw milling marks are carved into the surface of the article, replicating the circular saw milled texture.
