Effortless Metal Nut Cracker for Chestnuts Pecans

Physical specs: 18.5 cm long, 4.5 cm wide, 2.0 cm thick; weight approx. 120–135 g based on material density and volume. Primary materials: structural metal frame (load-bearing arms and jaw) + high-impact plastic body (grip zones and housing). Intended for manual, hand-powered operation only. Functional principle: a Class 2 lever system where the fulcrum is positioned closer to the nut cradle — amplifying applied hand force at the cracking point. This allows reliable shell fracture across chestnuts (with thick, curved shells), pecans (ridged and asymmetrical) and hazelnuts (smooth but dense). Designed for frequent domestic use: fits standard UK kitchen ergonomics — comfortable for average adult hand size, usable on countertops or small prep boards. Ideal for batch preparation before roasting, snacking, or incorporating into recipes like chestnut soup or pecan pie.
