Trying to find out what bladesteel type is on what seems to be a german import m4 bayonet likely made by eikhorn. Ive nearly exhausted my google fu trying to find it myself, thought might be some expert here with the knowing.
 
Not much help, but according to our Robot Overlord chatGPT:

"Eikhorn is a well-known German manufacturer of bayonets and other edged weapons, and they have produced a variety of M4 bayonets over the years. However, without more specific information about the particular bayonet you are referring to, it is difficult to determine the type of bladesteel used in its construction.
Some Eikhorn M4 bayonets were made with blades constructed from high-carbon steel, while others were made with stainless steel. The specific type of steel used could also vary depending on the year of production and other factors.
If you have access to the bayonet in question, you may be able to find more information about its construction by examining the blade and any markings on the blade or handle. Eikhorn typically marked their bayonets with a variety of symbols and codes that can provide clues about the blade's composition and other features.
Alternatively, you may be able to contact Eikhorn or a reputable bayonet collector or dealer for more information about the specific bayonet you are interested in. They may be able to provide you with more detailed information based on the markings and other characteristics of the bayonet."
 
A picture could help.

For the past few decades, it has been the 55Si7 steel.
 
Probably a German D95 (SAE 1095) or D75 (SAE 1075), the later is pretty common for German knives across the board. Newer production blades are usually in 55Si7, but I don't believe that it is the case with your bayonet.

Thanks, so sounds like its probably halfway ok carbon steel, with maybe halfway decent heat treat?
 
Eh, simple carbon steels are pleinty good for most usage, I have even lower grade simple carbon steel knife that are plenty good, other members here have the same knife with the same experience. It is not expensive steel, but it is more than "half way ok". If it was made for the US military contract, it is likely in D95/SAE 1095.

The bayonets are usually softer than a dedicated knife, because its main usage is for stabbing with cutting is more of the secondary usage, give or take. With the leverage of the rifle, it is very easy to break a blade. It also saves a lot of money since the thing was mass produced.
