HP plotters

I've seen knife assemblies which fit into the pen holder on the plotter.
Unfortunately I don't believe it's realistic to use them on the HP multi-pen
plotters because they won't fit in the carrier.

The one I examined had three roller bearings (implying it's runing on a
flatbed, BTW) with a swivel mounted (obviously quite meticulously assembled
as they're less than 1/2" in diameter blade centered between the rollers.
These rollers are in a barrel which is what the plotter grabs and align
themselves with respect to the direction of travel so the blade, which is
spring loaded and height adjustable for different thicknesses of vinyl.
I've never seen one working on a drum plotter like my 7585B, though.

I'd really hate to have to build one of these things.
