I just got my Alaskan Guide series Buck Vanguard. It is made of s30v steel. If you want to see a knife that will last forever and retain its edge forever, you should look into it. There is some crazy good steel out there if you do your research. I don't know much about Cutco or what steel they use, but I got excellent craftsmanship and the forever guarantee with my Buck for just over a hundred bucks.
