The Dexter S133-7PCP Sani-Safe? fillet knife is perfect for slicing crappie, perch, bluegills, and other small fish. The thin blade easily fits between the skin and top layer of meat. The flex points in the blade allow it to bend while fileting and then snap back to its original shape. The edge is individually ground and honed to ensure it is sharp right out of the box. The blade is manufactured with DEXSTEEL? high-carbon steel, so it is hard enough to hold a super-fine edge for a long time.
