Step 2: Recut the same lines again, but this time I use a 90 degree V-graver. Again, I cut as deep as I can WITHOUT widening the first set of wide graver cuts. Above, you can see the difference between the 116 degree cuts (left of the blue arrow) and the 90 degree graver cuts (right of the blue arrow).
Above, a closeup of the 90 degree graver cuts.
Step 3: I use an onglette graver to continue deepening the cuts. Again, I’m cutting as deep as I can without widening the previous cuts. Above, you can see the 90 degree cuts to the left of the blue arrow,and the onglette cuts to the right of the blue arrow.
Above, all three steps together – 116 degree graver on the left, 90 degree graver in the center, and the onglette cuts on the right side. Next, we’ll begin to carve the interiors of the cuts with flat gravers and begin the 3D-ish part of the shishiaibori process.
Thanks for Looking!
