Forrest's blades offer a superior cut that leaves a rip-cut saw edge that is as smooth as if it had been sanded, and a cross-cut edge that is almost mark-free. The blades run very quietly, and backside tearout in plywood is negligible. Each blade is virtually hand-made. The plate is hand-tensioned (up to 15 minutes per blade), superior C-4 carbide teeth are hand-brazed to the plate, and the blade is straightened and restraightened multiple times throughout the process. Think of a Forrest blade as a tool in your shop, not an accessory. Forrest stands behind it's blades by offering a sharpening service that bring blades back to the exact tolerances offered in a new blade. And this same exacting service is available for other manufacturer's blades as well, so they should come back better than new. The Solid-Surface Planer carbide-tipped saw blade is especially designed for: Avonite, Corian, Fountainhead, and other solid surface material where the "ultimate" smooth cut is desired. Specially engineered clearances on the carbide teeth totally eliminate chipping and side scoring. The Result... perfect joints that last for years. 50% to 300% Longer Life Between Sharpening - Reduced Yearly Sharpening Costs - Less Machine Downtime - Improved Labor Efficiency - Inventory Savings - Fewer Blades Required.
