I was helping a family member move today at a short notice so I did not have appropriate tools. I had to unhook a dishwasher today, I took my tenacious and pounded the back of the blade with a hammer to split very thick and heavy wire. Also it sawed a thick tube with the serrations. I also used it to pry nails out of the wall. The blade looked horrible but after a clean up and sharpen it is ready for another day. It now has a personality mark on the spine from the hammer. This is a great value.
