I just watched the youtube clip where the guy makes a bow with the Tracker knife. Look at how many blows he uses to cut that tree! 80 blows!!! And look at that tree, it's not a big tree... let me have a go at that tree with my Busse Ash or Black Jack Quick.... I rest my case : )
Well if you look at it, he really isn't hitting it very hard. It's not like Noss going trough a 2X4.
My thought was that he is able to do a lot lot of stuff with the tracker, not that there is not better knives out there.
