Tell me about the two dot, four dot thing.

So I keep seeing these threads with two dot blade and four dot blades listed in them. Is this a heat treat code, material code, or location code?

Date codes.

Best you go up and study Joe's sticky above on the 110s. That should answer all your questions.

Although they are date codes, they give clues to heat treat, materials, etc.
