Note from a customer about this knife: Just wanted to share some history on a knife you are selling SKU 418573 Imperial Nonmagnetic. What you are referencing as Hand Signed unknown initials is the Lo-Mu date or the last time the knife was run through a magnetometer to ensure that it met the Gamma rating for contact Lo-Mu or Nonmagnetic standards for the Navy. It's not someone's initials it is the letter L and the symbol for Mu kind of a weird M. Also I was originally told they where made of Beryllium, I believe some of the original ones might have been. The one you have is similar to the one I own and after some research I think these are made of Haynes Alloy not Cube they lack the copper color that CuBe has. I am a retired Navy EOD and specialized in Mine Counter Measures for most of my career. Just thought I would share so you knew a little more about it.
