I've mentioned it before ......................
I use an ordinary hacksaw to cut Hoffman's board material. VERY quick and very little dust to contend with.
Cutting a 12 " line with a hacksaw took me maybe 20 - 30 seconds. I just clamped the board down. I then hit the edge of the cut board with an orbital sander using 80 grit for just a couple of seconds and done.
with respect, Tubenit

Me too.

I took this to restore my apartment
so now I use it also for other things

before I used a cutter to engrave the board and then a pair of pliers to remove the excess

That's interesting - a miter saw that doubles as a table saw? I don't think I've ever seen one like that here in the US.

Hoffman's board material is fiber-glass reinforced.
It will dull a saw.
Hand hack-saw blades are less than $1.
Circular saw blades are $5 to $15.
Yes, if you do VERY little work with a carbide-tooth circular saw, it stays sharp.
With house and garage and loft and now the tractor-shed, I use my table saw a LOT, and replace the blade a few times a year.
Better to dull a $1 hacksaw than a $15 table-saw blade.
Also the glass dust is bad for your lungs. The circular saw throws fine dust in your face, the hack-saw dribbles crumbs on the floor.
A trick most of you do not need. You can make a large hole in Hoffman's board material with a metal-cutting hole-saw. This is tricky and maybe dangerous. I securely clamped dense Oak front and back, then clamped the whole thing on a work-bench. I should have used a heavy drill-press. With hand drill it does want to "grab" and break your wrist. (This gives me one 2" hole where there were several 1" holes in an electrical box; and very arc/flame resistant.)

Miter saw that doubles in table saw is very common here
however you must consider that the table saw is very small
---
The circular blades I use are much more expensive than $15
they have widia teeth and has a good durability
I must say that for my boards I principally use bakelite and only sometime fiberglass
