Enjoyed the video and I agree completely with regards to the integrity of the properly made narrow-tang. I have a number of custom-made, high-performance narrow-tang knives in my collection that will easily outlive many full-tang models (same collection) of similar size and steel under excessive stress conditions. I might add; I also have a few narrow-tang knives in my historic collection that helped settle this great country. The old narrow-tang knives are still here, while the makers and several subsequent owners have long been dead.
"Many of my early knives were full-tang; that's how I learned everything that can go wrong with full-tang knives. As I saw the results from rough use, abuse and even knives that had been lost and laid out in the weather for a season or two. This got me thinking about using narrow-tang construction. The exposed edges of a full-tang are an open invitation for loosening, breaking or such. Properly done, the narrow-tang knife is superior because it is a sealed unit and there is less to go wrong with it on a rough-use knife."

I have little clue as to what a "bushcraft knife" is since its definitions seem to be as diverse as the members and skills here on the forums (yes, I know all about Ray Mears...and a few others). My generation, here in this country, in these parts, still use the basic term, "camping and woodcraft." I suppose the tool requirements of either are not too dissimilar and the properly made full or narrow-tang would fit the task equally as well.
