The choice of the professional. High performance, virtually unbreakable bi-metal blades with 30% more cutting power and superb wear resistance. Cuts all types of metal including alloys, steels and stainless steels. The combination of an M2 high speed ground cutting edge, electron-beam welded to a flexible alloy back, gives a level of cutting power and flexibility that is far superior to edge hardened or conventional flexible blades. The unique ground tooth profile produces a faster and more aggressive cutting action that requires less effort and is more efficient than a standard blade. Made in Sheffield.
