The advantages of a serrated blade are already known from various stripping tools. UltraWiz proves with these serrated pull knife blades that serration also offers advantages with a hand-held blade: the pointed teeth pierce the adhesive bead when the blade is pulled. In combination with the thin cutting edge, this makes the cutting process much easier. At the same time, the blade can be resharpened on the outside without losing its teeth. As a result, the blade has a very long service life and can be used with all pull knives in our range.
