Review on Effortlessly Cut Through Metal with Malco JCCR J Cutter - A Reliable Tool for Precision Metalworking by Adam Wilson

Climbed my whole house all by myself. This made cutting the J-channel grooves faster and easier. After a while I stopped just cutting "tabs" and switched to full slots. Then, instead of bending the tab at the corners, I just stuck a piece of weatherproof tape in the channel j. The tool is a great time saver.
