Review on 📐 Alvin Aluminum Graduated T Square 12 Inches: Precise Measuring Tool for Drafting and Technical Drawing by Tim Curd

This T-Square works great. I use this for craft/art/decal projects. For these purposes, the ruler seems really strong. Bought after having trouble getting straight lines with my other rulers. I want to warn people about some of the quality issues I've encountered. The first one I received had several deep cuts on the underside of the blue head - it looked like someone held a utility knife on it and cut some lines. The raised/cleaned bits of plastic were still attached to the ruler and scratched my hand (and no doubt scratched the art paper I was planning to use it on). So I changed it to something else. And the second one also had a scratch/dent on the blue head! I didn't have enough time to make a third exchange and since the damage was minimal I decided to push through. I tried to fix the situation by scraping the raised, crumpled part of the plastic with a rougher sanding pad to avoid scratching myself or my art paper.
