Delivery was right on time. The knife was like sex; I knew I would like it before I got it! Ontario is one of my favorite companies! They don't waste their time or mine by building trash. This thing is a HOSS!! Oh yeah, the wire cutters are not just there for looks either!

Item I received was a new, in commercial box, 2019 manufactured M9 bayonet. Thought I was getting a used, surplus M9. So for the price, I think its a good deal.
