Gorlitz™ knives and blades are extremely strong and yet are flexible enough for any sewer or drain cleaning job! All Gorlitz knives are die cut and formed when in a soft condition and then heat-treated to our specification. In addition, they are black oxidized and oil dipped to prevent rusting. These hardy blades are offered in many different shapes and sizes depending on the drain or sewer cleaning job for which they are needed. Whether you need to cut roots, paper, diapers, napkins, grease, sludge, etc., our knives can even be hand sharpened for a special cutting job. Available with plain or serrated cutting edges, these blades are used with 3/8″ up to 3/4″ diameter cables to clean sewer lines from 1 1/2″ up to 8″ in diameter.
