The sticky tape method works as long as the adhesive bonds well enough to prevent stretching. It works best on wide thin bands with a clean surface. On Thera-band, you must stick on the non-talked side. It did not work for me with Linatex.
You need a sharp knife. A hard surface like granite, steel, glass or ceramic will blunt a round bellied blade. It will also blunt the very tip of a straight edged scalpel because that is the only contact point.
A rotary cutter will always be superior to this technique, but should be done on a soft plastic cutting mat. Rotary cutters are cheap and asy to buy and you can combine the tape and rotary cutter.
The bestway remains a steel rule die cutter.
