im new too graffiti and i just wanted to understand what are good and popular tools to use to carve tags on mirrors sinks etc. Iv been using regular rocks but sometimes its kinda hard to write since its all deformed. one thing i noticed is that rocks wont carve into sinks and barely into soap dipensers so i wanted to know good alternatives for that. last thing if you guys post tools please put what stores i can get them if they are in stores. thanks guys :p
