Faithfull's Bi-Metal BiM Multi-Tool Blades are a versatile and durable option for various cutting tasks. Constructed using two different metals - high speed steel (HSS) and high-carbon steel (HCS) - these blades combine the hardness and heat resistance of HSS with the flexibility and shock absorption of HCS. This makes them ideal for heavy-duty use and cutting through a variety of materials, including wood and metal, with Faithfull's Speed Edge technology for faster, cleaner cuts and reduced wear.
