Sheffield plate
Sheffield plate is a layered combination of silver and copper that was used for many years to produce a wide range of household articles. These included buttons, caddy spoons, fish slices, serving utensils, candlesticks and other lighting devices, coffee and tea sets, serving dishes and trays, tankards and pitchers, and larger items such as soup tureens and hot-water urns. Almost every article made in sterling silver was also crafted by Sheffield makers, who used this manufacturing process to produce nearly identical wares at far less cost.

Men certainly grow strong enough hereabouts, but I doubt that their hand-drawn bows will put a quarrel through good Sheffield plate, although it probably would through leather.
