SMART CARDZ ARE A CONTEMPORARY VERSION OF THE TRADITIONAL HARD CARD...BUT BETTER, BECAUSE THEY ARE 25% WIDER AND HAVE A COMFORTABLE GRIP AND THIN EDGE.THIS IS THE NEW & IMPROVED TEFLON HARD CARD
I like this card because of the large grip and wide thin blade. I use it for heat shrinking, it may scratch the film so get the felt tip for installation uses.
