This was a fun request to forge a knife and bottle opener out of a wrench. The steels used for wrenches are pretty tough as they are meant for some serious torque and use. If you have a wrench I am more than happy to use that as well. Make it a 1′ since I noticed I needed to open up the 7/8″ as shown in the picture.
This is even heat treated and sharpened to hold an edge. Just in case you are skinning a moose and you know…you want to open that beer.
