What kind of steel use on old LB7 USA made knife?

[m10commander]

Hi guys, I have a USA made LB7 folder & I wonder what kind of steel use on the blade? Is it stainless steel? Any info would be appreciated! Thanks

if it's marked schrade + on the tang it's stainless.

To be just a bit more specific, the earlier ones were 440A and the later ones 420HC, if I remember correctly.

On our Uncle Henry line and Heritage line we use AISI 440A stainless steel. Knives with this steel will have a Schrade+ in their tang stamp. 440A gets its stainless properties from the inclusion of 17% chrome with 0.7% carbon in the steel. We have found that 440A is equally as good a cutlery steel as 1095, as well as having the added benefit of a high degree of stain and rust resistance

Thanks guys! Mine has Schrade+ stamped I bought it in the 80s originally I wanted a Buck but the LB7 was cheaper & both knives were very similar in size. I recently found it in my closet I was surprised it has no rust on the blade only some green stain on the brass bolster.

WD 40, toothpaste, or any good metal polish will take the verdigris (green patina) off for you, posthaste. Enjoy that nice knife.

I may have seen this before, and I know this is an old thread, but I wanted to say THANKS for digging this information up.
Helped with my research.
