Australian M9 Bayonets

New - Australian M9 Bayonet
Very similar to the US M9 Phrobis / Buck bayonet.  BUCK sold 20,050 bayonets to Australia in the early 90's and is still in use today by SAS and elite infantry units.  The markings are 'BUCK/188/USA' with an Australian broad arrow military proof mark stamped after the '188'.  The scabbard has the normal 'BUCK' marking on the front but does not have the broad arrow mark.  Fastex dated 1995.  Very hard to find.

United States M9 Bayonets

US M9 Phrobis Gen 1 w/Chevron
Buck manufactured the first M9 Bayonet model for Phrobis (Gen. 1) in 1987. They are marked on the obverse 'M9 over PHROBIS III over U.S.A. >'.  It displays the 'flat top M' found on only the earliest M9's.  Buck, without the knowledge of Phrobis III, added their code ' >' (dated 1987) to the first 1,200  bayonets. This was not in keeping with the Technical Data Package and Phrobis instructed Buck to immediately remove the mark from any subsequently manufactured bayonets for the military.  Only about 1,200 pieces were marked with the '>'.  Green waffle style handle and scabbard.  Gray blade with sharpening and in/out wear.  Green 4 slot scabbard with unused sharpening stone with pouch and Bianchi attachment.  Only about 1,200 pieces were marked with the Chevron '>'.  Rare.

US M9 Gen 1 LANCAY General Cutlery Bayonet
Lan-Cay received it’s first contract for 30,500 M9 bayonets on 3/31/92 from the U.S. Army with an additional 21,500 bayonets added during the contract. In an effort to quickly supply the Army with new M9 bayonets after Desert Storm, Lan-Cay turned to General Cutlery as a sub-contractor to provide near completed blades for assembly at the Lan-Cay facility. All General Cutlery produced blades are easily identified as they are stamped on the ricasso "M9 / LANCAY / USA" in block letters of equal size. This form of marking was used only on the General Cutlery made blades and was never used again. This piece has the correct unmarked pommel (no LanCay marking), screw driver at the end of the cutter plate on the scabbard and 1992 dated fastex connector.  Green waffle style handle.  Fullered blade with in/out markings and sharpening.  Four slot scabbard with cracked sharpening stone with pouch.  General Cutlery assembled M9 bayonets are extremely rare with only about 300 units made.

US M9 LanCay Bayonet - PI Model w/Gray Blade
Toward the end of the 1st contract in 1994, Lancay produced an M9 that exhibited major changes to the blade design that is obvious upon inspection.  The "step" on the back of the blade between the sawteeth and the guard was eliminated. Also the sawteeth were shortened.  Additionally, even though this knife obviously has a second contract, P.I. (product improved) blade type, the blade color remained the same dull grey finish of the first contract.  The blade shows some spotting in the gray finish overall with no sharpening.  It also exhibits first contract labeling of the manufacturer (LanCay) instead of the 2nd contract type labeling (Lan-CayAY) for a product improved blade.  The scabbard was the later 2 slot version without a sharpening stone with an angled screwdriver tip with the Fastex dated 1994.  There were only 1064 total M9's produced in this configuration to fulfill the 1st contract which makes this variation quite rare.
