Used to trim the metal liner and grate of the chimney. The grate had metal protrusions that held the grate in place. The grate for cleaning the firebox has been moved and the protrusions are bent outwards. Instead of bending the tabs, and perhaps for safety reasons, use this tool to cut off the tab and then grind away the remaining metal on the grate. No more worrying about catching your tongue on your finger or glove. The tool only needed a firm grip to make a precise cut with a single press of the tool. Also, cut through the wire mesh like butter. The handles are sturdy and just right for big hands. The craftsmanship is first class, using first class materials as well as precision tools. These scissors will be widely used in the future. If you need to cut metal, wire or fence then this tool is for you.
