This high-quality OEM Challenge 193 H-Series replacement cutting blade is designed to provide superior cutting performance and extended cutting life. It is always a good ideal to have an extra blade or knife on hand when you send your other blade out for sharpening or in case you need to replace a blade that has been repeatedly sharpened or has become nicked.
This knife has a bi-metallic composition consisting of one part high-alloy tool steel and one part standard grade steel. A special fusion process bonds these two together to produce a high quality knife at a great price.
