For Unona Knife, at present, China’s general factory is still lack of specific information; especially its cutting consumption, the factory is still exploring their own. I plant recently made a longer trial, the initial understanding of the superiority of this tool, now these experiences are introduced as follows: First, the cutting test conditions Before the test, respectively, forged cast steel (45 steel ), Mild steel (20 steel), and gray cast iron test sticks. The machine used in the old Japanese all-gear lathe, horsepower 15 horses. According to the original UNA-NON knife tool, the angle has not changed.
