US M9 LanCay Bayonet - Transitional 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.  It also exhibits first contract labeling of the manufacturer (LanCay) instead of the 2nd contract type labeling (LAN-CAY) for a product improved blade.  The scabbard has 4 slots with a sharpening stone with the Fastex dated 1993.  Only 1064 total were produced in this configuration to fulfill the 1st contract which makes this variation quite scarce.

​US M9 Lan-Cay Bayonet - Transitional PI Model w/Gray Blade
A few very rare Product Improved (PI) models marked M9/Lan-Cay/USA (with hyphen) with a gray blasted blade (which should have black oxide blades for the standard PI models) which were used to help complete the requirements of the 1st contract.  It is a standard 2nd contract type M9 with Product improved features of the blade and scabbard but with a gray blade. Standard waffle type round handle.  There is no blade fuller on the blade.  It is not known exactly how many of these were made but they were only made for 1 to 2 months and would be estimated at less than 3000 in total.  For some reason, this particular bayonet has had the waffle green handle replaced with the newer ergonomic handle and the scabbard has the 2 slot scabbard with no sharpening stone and the fastex is dated '01'.

​2000s US M11 Lan-Cay Black Aluminum Handle Bayonet
Per Bill Porter - The M9-LW Lan-Cay (for Light Weight) with black aluminium handle model has the guard & tang rod in aluminum, built as a commercial M9 knife, by my friend, Mark BAKER AKA Unnaturalone, an old Ebay M9's seller.  Some M11 EOD knives have also been found with these tooled black aluminum handles. One blade has a bead blasted silver finish and the other was a black oxide finish.  These had no scabbards.  

Black aluminum handle, marked EOD over M-11 over Lan-Cay on the ricasso. bead blasted blade.  No scabbard.  Excellent condition.  From Bill Porter collection.  Very rare.

Per Bill Porter - This is the incredible story, of my friend Mocityman, www.MOCITYMAN.com about these aluminum grip handle, built on these M11 EOD bayonets.  These handles came from a company that also makes artificial hips, they were going through a split, with one owner making medical parts and the son was getting into rail systems and weapon parts. He was going to make a full version of the M9 but never did.  He contacted me and wanted to get rid of them because he had no way to sell the handles and gave up on making a knife once he realized how hard it is to make a blade correctly. So I went all in and bought them along with some other parts he had made for rifle swivels and some other junk that was not M9 related, it was a big choice to make I made it because I knew it was an item no one else would ever have.  So, I tried to find them again years later and I think they went out of business just have a gut feeling that that is where they were headed.

US M9 Lan-Cay Bayonet - Unmarked Factory Sample
A few Product Improved bayonets have been found with no markings on the blade or end of the pommel and the blade is unfinished (ground and sharpened).  The blade has no fuller, has a black oxide finish and the scabbard is marked Lan-Cay and the Fastex is dated 1998.  It is thought that these few bayonets were removed or stolen from the factory by employees before the bayonets were finished for sale or were used by company executives for personal gifts.  Only a few have ever been found.  These are very rare since only bayonets with full markings were used for Military or Commercial sale.
