Hello, I'm new here and this is my first post. I recently picked up a used Strider and would like to ask the group if they can educate me a little bit as to what model it is that I actually have. I was told that it's an SGN and judging by some of the pic's I was able to find online I think that is correct. There is some blue hardware on the clip side that I'm wondering about, is it factory or after market? The seller didn't know. Thank you very much!
