This is part of my corrugated knife collection that I used with my shaper. Tons of different profiles. Crown, base, table edge, cove, raised panel, flute, ogre, and just about everything else. The shaper head is 4” diameter and 4” height. Please study the pics. I am open to serious offers. The shaper head is for a 1 1/4” arbor shaper. These typically run over $300 alone new. If you have purchased moulding or knives you know this stuff is very expensive now! If you like playing around with moulding then this set is for you. Please ask if you have any questions!!
