Nordnecker, I see what you are trying to do, I misunderstood your question, sorry. When you said zig zag, mu post is whatI thought you meant Iuse both methods you mentioned as well to cut deep triangles. I have reground onegraver to about a 135 degree V and used it to cut the triangles toward the scribed line. The problem is just what you described, getting rid of that burr. I prefer your second method, it does take practice to get the rhythm down so your triangles are even, I find it feels like when you make your first cut, you go in shallow and come out steep, sounds odd but it make the triangles come out even. Especially when doing the second row of triangles like you are.
