Hi Jtallant,
Sorry for your experience. While it is hard to imagine that one of our knives wouldn't cut the line, I guess it's possible. I'm glad Customer Service is sorting it for you. I've been out of town. I'm going to personally inspect your knife when it comes in.
Anyone that says a plain edge knife will cut line (rope) better than one of our serrated versions has, in my opoinion, very little experience with line and serrated Spyderco's. We stopped using Poly rope in our demos becaue the line seprateted so quickly, it looked like defective line.
I have experienced failure at cutting poly line with a straight razor, so "bite" is a good feature on rope.
If I'm on my boat, my knife is serrated. period.
Let me know if you want to try one with teeth in our replacement.
