Bi-Metal Trapezoid Knife Blades combine the best of two metals electro-welded together.
Edge of the blade is made from high speed steel, which is much harder than standard carbon steel.
Shown to last up to three times longer in user trials on plasterboard, drywalling, roofing, insulation, flooring and other heavy-duty materials.
Bulk of the blade is made from spring steel, which can resist pressure applied from the side without snapping.
Safest blade to use is generally a sharp one - as it takes less effort to cut, and therefore greater control can be maintained.
Stays sharp up to 3 x longer than standard blades.
High-speed steel edge, and heat treated to greater hardness for longer life and edge sharpness.
Fits all standard knives.
NB. Currently these blades are plain and are not blue striped as depicted in the images.
