Tips and Techniques: Curved glass technique (Part 2) 

MutilateTheDead Thanks for the great feedback!

I agree with the review. Explained very well.Thanks for posting.

There are two types of metal used in tint knife blades and scrapers, carbon steel and stainless steel. Carbon steel is most commonly used in scrapers where you are scraping / sliding over the glass versus holding the blade perpendicular to the glass and cutting. Stainless steel is softer than carbon steel so SS is used by most for any direct on glass cutting. Note however if you push hard enough even with a SS blade it is possible to leave a cut line in the glass so the tip is to use a sharp fresh blade with minimal pressure needed to cut the film. The blades used in Olfa knives which are the most common cutting knives are segmented to snap off so after say 10 to 15 cuts you should snap off the end of the blade to expose a new segment maintaining a sharp edge. Some glass can even be softer than others so some tinters place a 1cm x 1cm piece of thin plastic under the film where they want to cut then position the knife blade so the tip is into the plastic through the film. Then as they drag the knife along they are sliding the plastic with it meaning the blade itself does not touch the glass. This technique is only really suitable for rear screens where there is clear area around where you are cutting. You can’t use this technique for cutting the edges on house windows for example as the plastic would space your cut line too far off the window rubber leaving a large gap. Most tinters though have no problems by just keeping a sharp blade and watching their pressure cutting on the glass. I hope this helps
