Material type is one of the most critical factors when choosing planer and jointer knives because it directly impacts durability, sharpness retention, and suitability for specific woodworking tasks. High-Speed Steel (HSS), especially T-1 with higher tungsten content, offers excellent toughness and is easier to sharpen, making it ideal for general woodworking and softer woods. Carbide-tipped knives provide superior edge retention and wear resistance, perfect for high-volume shops or working with abrasive or harder woods. Available options include HSS, T-1 HSS (18% tungsten), and carbide-tipped varieties. For example, the Amana Tool P 390 uses high-grade T-1 HSS for hardness, while the Amana Tool CTP-170 is a carbide-tipped option for extended life. A wide selection is available to match specific needs.
