I would have a hard time picking the "Best" up and coming Bladesmith, since I love the work of most of the makers that have been listed(havent seen some of it yet though), but I will try.
Ok, I will put my vote in for a guy who has been a stock removal maker for about 30 years, but just recently got into forging his blades. Evidently, the transition went smoothly, as Russ Andrews's forged blades were judged good enough to win the George Peck award for best knives submitted by an applicant for Journeyman Smith at this year's Blade show. There have been pictures of Russ's work in some of the recent knife magazines, and I have posted a few pics of Russ's work here from time to time. Simply awesome!
