Need help with blade markings

[olpappy]

Hi,

I bought this knife recently and have never seen these markings, would like to know if anyone recognized these markings? Thanks in advance

You mean the Sal and E (for Eric) Glesser?

Just a rookie here, but I believe that is a Spyderco knife and those would be Sal and Eric Glesser's marks.

Yeah, exactly. I haven't seen those before on my other Spydies. Thanks.
