Good morning all, I had to pass this on: If anyone does sheet-metal work, this Nibbler I bought does a great job. http://www.amazon.com/Klein-Tools-76011B...eywords=nibbler I just increased my homes downspouts from 2x3 to 3x4 inch. I had to install larger flanges in the gutters and this 'Nibbler' was just the tool to use. It was way more precise than using tin-snips. Made in the USA and replacement cutters can be purchased. It made my life easier. I highly recommend it.
