optimal for small strains

this riving knife is my discovery of winter. Affordable and solid he drives into the wood, without that it was touched upon earlier. He splits in 2 - 3 parts. The wedge is optimal when the trunk has a smaller diameter of less than 15 cm and you want to save yourself the scribing. These pieces are broken clean and simple. Large and persistent strains can wedge already spit out times, as a pimple. The wedge is made of solid steel and will not distort. It can be recessed into the wood, so that the strain on the piece can be further processed.
