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

Works well for the most part. I think in cold weather the j channel shrinks making them a little too big to fit in 5/8 j. Can't wait to see if they work better as it warms up. I would still recommend it because I'm pretty sure I'm getting the temperature right, which makes channel j difficult to work with.
