When I really discovered how great the fully Serrated/Spyderedged Native model is I was facing a really nasty and demanding job in which I had resigned myself to believe that whatever knife I used in that job was going to be destroyed. It was a very mean job and I even destroyed a Stanley box cutting knife but the fully Serrated, 440V, Golden CO USA made Native survived and I still use that knife a lot on hard use type jobs.
I don't believe I've ever put any of my Spyders through as hard of use as I have my 440V SE Native model. The new Native 5 in full SE is high on my "gotta have" list of Spyders I intend on getting in the next two months or so.
That Spyderedge Native is truly a super rugged folding knife and I highly encourage anyone to consider having one in their survival kit, bug out bag or even as a major back up blade. And I'm still on the lookout for another 440V SE Native for my survival kit.
