Will this knife really work with an AK47 ?

[hafool]

Has anyone ever seen this knife before and can it really be used on a bayonet? It is said that it can fit together with a AK47 rifle. Maybe it is a copy of some old military knife that was used back in one of the wars? The website that it is on is FREE Shipping Of Wholesale Items China Direct Wholesaler Distributor I am wondering if it can fit on any other types of guns or rifles. Does it look like something that would be used by Chinese, Koreans, or Russians. Here is a link to the knives page 100's Of Knives Wholesale Online Ordering Shipped Direct From China and it is the knife with the number 406023 right at the top of the page.
Any help would be appreciated before I order it all the way from China
