Cutting Silicone Hose

[Railroad]

Any tips on cutting a 4" silicone hose?
I might need to reduce the length on a 4" silicone hose. I want the cut to look clean and factory. I have considered sliding a 4" alum tube inside and cutting with a sharp instrument, razor, etc.
This stuff is very tough and I do not want to try a method that does not get the job done and have to start over.
I have a band saw, but do not think it will leave a clean cut.
I will appreciate your ideas.

I asked a friend of mine who has done this on his car. He said you can use a clamp tightened around the hose as a guide, make sure it's square, and use a utility knife with a new blade. A bit of soapy water will make the blade slide easier, but be careful as the hose may become slippery, too.

Yes the clamp works good. Get it in the right place and sharp cutter.

Thanks for the clamp tip. I was aware of its use on tubing, but it went right over my head on the hose.
I think I can slide the alum tube inside, measure and square the clamp, tighten and cut.
I feel comfortable about it now.

Clamp works, clamp AND sliding it over tubing works best, but is tougher on blades.
