If you truly want an M9 bayonet to use as a tool, by one of the Medrano M9s that are made in Taiwan. They are a good copy of the US M9 bayonet and only cost about $40. If that isn't what you're looking for, then check ebay. There are always a number of them for sale there. You can get one of the current Lan-Cay bayonets for under $100.
Your name and your reference to "homemade" lead me to believe that you are located in China. If that is true, it is illegal for anyone in the US to sent you a bayonet. Where are you located?
