A couple of quick reactions. I thought that the Angle Cube has a zero set button so that you can place it against what you are using as vertical (or horizontal) and set it to 0, then against the stone being used on the WE to get a relative angle?
Second thought, it occurs to me that you could use the WE as a make shift laser goniometer. Place your knife in the holder, as you would to sharpen a knife, then suspend a cheap, laser pointer above the knife edge facing down, then see and mark where the “bubble” laser images hit on each side of the base. Once marked, take a straight edge with the Angle Cube and determine the angle. It doesn’t matter how high above the knife edge you suspend the laser, as (since it is collimated, going straight down) it will be deflected the same number of degrees to each side, based on where it hits the edge and the edge angle, independent of how high above the edge your laser pointer is. Clear?
I’m going to Home Depot or Ace today and see if I can find a stand to suspend the laser pointer above the edge, so I can try, take a photo and clarify what I have in mind. But it may be a simple, doable way of creating a home-made goniometer that gets past the 1.7″ blade width limitation of the one from CATRA.
