Honing Heljestrand safety razor blades

Does anyone know how to hone these blades? I just fancy using one of these someday.

Over on Eboy you'll see these safety razor sharpeners like the Lillicraps which they used to use years ago. I don't know if there is something unusual about the blades your looking at. If there is maybe there is some dedicated sharpener for it like the rolls razors have.

You need to make sure you get the full kit - it should come with a blade holder for honing and stropping the blades. Once they're in the holder you hone and strop like a straight. The lillicraps device is for stropping DE blades.

Edit: In that kit you linked to, it's the widget to the right of the razor in the box, and to the left of the razor in the unboxed view.

Mparker: the Kindal thing holds the blade for stropping, a leather strop fits into it and I get the impression you pull the leather forward and backward to strop. However I don't see how you can use it to hone unless you take a different leather and apply some paste with honing particles.
