Kudos for Tormek customer service, for sure. However - I've noticed (and I've seen this posted elsewhere also) that the knife jigs do not hold the knife perfectly centered on the long axis of the jig. In other words, when you clamp a knife into either of the jigs, only one side of the jig adjusts outward to accommodate the knife; the other side is fixed. So, the thicker the blade, the greater the offset. For knives of "normal" thickness, such as kitchen knives, the offset probably won't be noticed. But for thicker blades, the result is very noticeable, even problematic, because you end up with a difference in grind angle, and therefore bevel width, on each side of the blade. I'd love to hear from Tormek with any advice on this issue.
In theory this could be addressed with a different knife jig, but it seems like a difficult thing to engineer and still maintain the strength and simplicity of the existing jigs.
