Reflective Safety Tape What Tool Is Sharp Enough To Allow Me To Cut Any Pattern I Could Draw With A Pen?

What tool is sharp enough to allow me to cut any pattern I could draw with a pen? - reflective safety tape

I cut the patterns of reflective tape security tape that I have on my bike. The knife cut just does'nt. You will receive jaged lines and the band moves when you cut the edges. A low-power laser, it would be perfect, because the problem is that I found on the band, how to cut butter ... There is no resistance, so you can keep my lines during the cutting.

I need a better technique or a tool for better quality, or both. Please help, I searched everywhere on the Internet and make calls, but no luck. Thank you.
