Nice tips, Nick. I've been doing something similar on my smaller kitchen knives (even before watching the video). The difference for me was I only radiused the spine of the knife, not the tang. It created a very interesting effect, in that it made the blade look significantly thinner than it did previously. My wife has commented about how thin the blade was (compared to the Global I was copying), but in fact it was about the same thickness.
Of course mine doesn't look NEAR as professionally finished as yours. Now at least I know how to advance the technique. Thanks.
