Pros : Although I don't use Cascade brand zinc, copper, or brass, the notcher is easily adjustable and can be used with most any brand. I make sun catchers in the shapes of crosses and love to wrap them in copper. With the notcher, the corners are so perfect that I don't even need to solder them. It not only saves a ton of time, it makes everything look more professional.
Cons : The base is a little lightweight. It's meant to be attached to a surface, but I wanted mine to remain mobile. So I attached it to a 2x4 board.
Other Thoughts : This is a must-have for anyone who uses the stiffer metals for framing and wants beautiful, perfect results.
