Default Kerfing chipboard

I know how to kerf ( even if I haven't actually done it yet) but I have never seen chipboard kerfed before, only thicker MDF. Is it possible to do with success or is this technique limited to MDF and good quality plywood.
I would like to finish the front of SWMBOs new bedroom speakers with a curved surface on the corners.
Top and bottom I'll make a template and use the router as suggested in the design thread.

the commercial kerfed sheet goods using PB as core will generally have the smooth face laminated with a thick paper, single ply of veneer( TimberCore), or even a HP P-lam ( Formica, Arborite, choose your favorite brand - but any will cost more than the core)

without such a sturdy face kerfed PB will likely disintegrate easily (possibly even before it's off the table saw), and even with it, the material needs reinforcement for structural integrity

That would explain why I have never seen it before then.
OK
Rather than use MDF here I will redesign for a flat front until I can get a workshop and experiment.
Thanx

there's always "Rubber Ply / wackywood " or any number of generic / trade names for making curves - but no matter what material / fabrication technique employed, CCM - curves cost money, and some type of support frame is required, even if temporary when cold pressing or vacuum bagging .
