The Guarded Orange Knife: A Guard That Sets the Cut to the Peel, a Nut-Pick at the Other End

Peeling an orange with a knife cuts into the fruit and lets the juice run, and prising the peel off takes the fingernails. Harry M. Hamrick of Philadelphia received US 461,914, dated 27 October 1891, for "a simple implement especially designed for cutting the peel of oranges, and adapted, also, for use as a nut-pick, and also to the removal of the peel from oranges after the same has been cut": a handle with a blade at one end, preferably with two cutting edges, beside a convex shield that regulates the depth of the cut to the thickness of the peel, and at the other end a pick curved at its outer end to go between the cut peel and the fruit, or to pick nuts. This rung works out the peel's share and the depth to set, then files the blade and guard, fits a pick at the other end, and peels oranges and picks walnuts.
