A combination wrench is a very simple tool but its certainly not simple to make one, especially a high quality one. Although we specialize in, and only sell German Tools here at KC Tool, we still have respect for other high quality tool manufacturers like Beta from Italy and of course Snap-on from the good ole U.S. of A. Beta Tools sent us a link to their video about how Beta wrenches are made and quality tested. I wanted to pass it along since it’s a very well made video and very interesting to watch if you’re a fan of tools and how things are made. Enjoy.
