Stone tools were most recently found by scientist at a dig sight in Israeli.  The tools appear to be just like a 'Swiss Army Knife' that were used to butcher animals. The butchering tools were found near bones of ancient animals in Revadimin, Israeli. The scientist believe that they date back nearly a half a million years. They found several different tools including a land axe.

I thank them for coming up with the idea. I use my 'Leather-man' almost everyday. It is exactly like the 'Swiss Army Knife.'
