I have several 24" square black rubber floor mats with raised bumps on the
surface.

I need to cut some of them to size as accurately and cleanly as possible.

I was advised to use a metal straight edge and a utility knife. The utility
knife does not seem to cut sharply and deeply enough to make a clean
accurate cut.

Any suggestions would be appreciated.

How thick is the rubber?

Got a carpet knife, those blades are much sharper?

How thick are they? How many do you have to do?

Best would be a bandsaw with a knife edge blade, but you need the saw and
have to buy a blade. I'd consider scoring (on the smooth back) with the
utility knife and following up with an electric kitchen knife.

I've seen jig saw blades with a knife edge. Even the right saw blade is
worth a shot.

I don't have one, but I will get one.

Thank you!

Did you try a brand-new utility knife blade?

The best way to cut thick rubber is to double it. When you cut, the kerf
opens up instead of closing in on the blade. Mark the rubber with a good
visible line on both sides. Use a utility knife with a straight edge clamped
in place. Cut half way thru, reverse and then cut from the other side.

Brand new blade is good. They go dull rapidly.

Lubricate the blade with soapy water-

I'm with Ed on the bandsaw- if you've got one it would be worth buying
the blade. You'll find other uses for it once you have it--- tires
make great sandals.g

I'll second that, I used one to cut up old tires, tried everything
else, and the blades with teeth just got hot. I made nice tree rings
out of sidewalls.

Reciprocating saw with general purpose blade. Cuts thru 4'x6'x 3/4"
stall mats like butter, so you shouldn't have any trouble cutting
through your material. Just make sure you have a good line to follow
and a good steady hand.

If you live in a cold climate leave them outside and try cutting
them when they're cold.
