Rotary riving knife from Fiskars splits particularly hard pieces of wood. Thanks to the notches in its surface, it has a better grip in the wood and can split more effectively. Its cutting edge turned by 90 degrees is also very practical. The Fiskars rotary riving knife is made of hardened C40 steel and has a Rockwell hardness of 36-42 HRC. With its weight of 2400 grams, it is very robust and handy. The head of the 24 cm long wedge has a special polymer face, which is coated with a metal ring. This serves in particular to dampen the vibrations that occur when impacting, in order to reduce the risk of possible material chips. The playing surface can be renewed if necessary. The riving knife fulfills the European safety standards and bears the seal tested safety. The exceptional design of this tool has won the prestigious Red Dot Design Award. In addition, it got the top grade from the DIY magazine itself, the man in the practical test is very good.
