Abstract: A trimmer comprises two counter-rotating barrels side-by-side above one cutting reel. When viewed from the front, the left barrel rotates counter-clockwise while the right barrel rotates clockwise. Plant material in the barrels accumulates on the uphill side of each barrel, relative to its rotational direction, as the plant material traverses the rotating barrels. This configuration positions the uphill sides of both barrels proximate to the one reel. The barrel perforations are rifled to assist in moving the plant material through the barrels. Screw jacks are employed to tilt the trimmer; hardware facilitates use of two such trimmers in series.

Abstract: Scissors, especially surgical scissors, having first and second elongate members each having a handle portion and a blade portion and being connected by a pivot between the handle portions and the blade portions for relative pivotal movement generally in a cutting plane during a cutting stroke. At least one of the handle portions supports a channel member having a length that extends toward, embraces and extends beyond the handle portion of the other elongate member to restrain movement of the handle portions out of the cutting plane and thus to resist relative lateral movement of the blade portions away from each other during the cutting stroke. The scissors are robust and are able to cleanly, effectively and accurately cut tough or slippery items which might otherwise cause the blades to splay away from each other.
