I've heard all the arguments about how bushcraft knives MUST be full tang or else!
In my opinion, a lot of people in the forums (who I think spend more time typing on the internet than they do in the woods) raise too much fuss about full tang construction. From my experience, unless you are intentionally trying to abuse the knife, I seriously doubt you're going to break a rat tail knife.
It's funny at how the Fins and the Swedes have been using non-full tang blades all this time and have managed to survive just fine in the woods. Maybe they didn't get the memo that what they were doing was frowned upon by the forum jockeys.
The most extreme task that you'd do with a bushcraft knife is batoning wood. If you are batoning correctly, the baton is striking the spine of the blade of the knife - not the handle. So how exactly you could break a blade by batoning correctly... It's almost inconceivable.
