The Mosher is a cord-powered straddle board parer. Amos Mosher of Galway, New York was granted a patent for his parer on December 28, 1829 (Thornton, 1997, p. 9). The cord-powered mechanism is essentially a pulley system that uses a large wheel to drive a smaller wheel providing a speed advantage. With every turn of the crank the apple rotates approximately 2.75 times.
Many hand-guide paring knifes require the operator to keep pressure on the apple. The Mosher hand-guided paring knife has a handmade spring mechanism to keep pressure on the apple using spring tension. A view of the underside shows the pins that help to secure the posts.
