Cutting Cut Comb - What Do You Use?

[Michael Palmer]

I suppose so but I presumed it was sharp out of the box.

I’ve used one of these before. Place it in the hot water, and use it to mark the cut lines on the capping. Then use your hot knives to do the cutting.

tried a variety of knives

Same here, and it's never 100%. I mean to try foundation wire: attach it to a U-shaped handle cut from ply and connected to a wire embedding gizmo: hot wire, thin and rapid cut.
