The Fallkniven and the San Mai Trailmasters are both full convex, ground to a zero poit edge. My favorite blade and edge grind BY FAR, especially when it comes to large choppers. :thumbup:
The SK-5 and older Carbon V Trailmasters are flat ground with a V edge.
BTW, You can turn a convex "edge" into a V edge, and vise versa, and you could flaten down a full convex blade if you had the ambition, but you can't really change a flat ground blade into a true convex one. .....hope that makes sense!
Personally I like alot of "big" knives, and I hope to own a Busse or two some day too. I've just always thought of the TM/Thor as sort of a good "Jack of all trades" kind of knife. That is maybe not "perfect" for any one task, but is "very good" at many. -Great all around blade rather than a single specific task tool.
