Lehman’s has sold a “Texas Pea Sheller” since at least 1993. It’s not known why Lehman’s names the product after Texas.

Tough nylon gears, aluminized steel body, no-slip serrated plastic rollers. 4"H x 4"W, clamps to surfaces from 3/4” to 1 3/4” thick. 2 lb, USA made.
Note: May bruise or crush some peas, especially if they’re not completely fresh and properly ripe.
