These heavy-duty shears will make quick work out of hard shellfish shells, poultry bones, and fish bones. One blade is micro-serrated for holding onto slippery surfaces while the other has a razor-polished edge that slices cleanly through tough shells and bones. The drop-forged stainless steel blades are some of the strongest we could find. They are held together by an adjustable nut with a quick-release joint so that you can maintain tight blade-to-blade contact and easily take them apart for cleaning. Strong enough to cut through a penny, these shears were designed for heavy-duty kitchen tasks. Slightly right-handed handle but we know some lefties who use them too. This item is made in the USA.
