Hi all,<br><br>I got a rotary cutter for making TB bands. When I cut along the my steel rule with it, it only cuts partialy through the rubber. The blade is sharp as I was able to cut leather no problem. The blade is in 5cm diameter.<br><br>Can anyone tell me if there is a certain way to use/hold the cutter while doing this, to ensure a clean line instead of the fraying I am getting at the moment. <br><br>Any help appreciatted.<br><br><br>Jenko022.
