Rubberized flooring

We have some rubberized flooring we bought last year for out CTC. Talked to an RV service tech, who recommended the right adhesive for it, the plan is to make a taped together cardboard template , lay that on top of the flooring and then cut it. Now I am wondering what will work best to cut it with. I have scissors made for regular vinyl flooring, but it is not strong enough to cut it. Looking for ideas and suggestions about what others have used.
