Para 2 blade markings?

[GrayDucker]

On my para 2 with brown scales and S35VN steel, on the blade are 2 different symbols, one looks like a goofy E with an arrow at the bottom and the second one looks like a funky S with a triangle underneath it.
My question is what do these symbols mean?

Thanks!

They are Sal (owner of spyderco) and Eric (his son) Glesser's logos. The logos appear on knives designed by Sal or Eric. The PM2 was a joint venture for them, hence both logos. For example, the caly series has Sal's logo, and the manix2 has Eric's.

Great thank you sir.

Might sound silly, but that's one of the reasons why I love the Manix 2 and Para 2. I like the look of their makers marks.
