I do a lot of bush craft type activities, you can pretty much use any blade for "bushcrafting." I personally wouldn't call a knife a bushcraft knife unless it could fulfill the following.
- Small enough to be convenient to use and carry.
- A nice long comfortable handle.
- Large enough to process wood at least as thick as my thumb with a cross-pull type cut and minimal fuss (3.5-5 inches. Much longer than 5 and it becomes more cumbersome to use and not as agile for wittling type jobs)
- Easy to field sharpen. (I LOVE the scandi grind for pretty much any bush knife. Easy to sharpen, easy to touch up.)
- Good edge retention. (Carbon steel is wonderful. Give the blade a touch of bee's wax and it helps prevent rust)
- Tough enough to take some batonning. Full tang is ideal. I also like a differential heat-treat from edge to spine. (edge being very hard, spine being somewhat softer)
- A nice square spine for fire steeling and fibre stripping (you can always square the spine up on a stone if it has a chamfer on it)
Couple of knives I like
Mora clipper (cheap and it does a great job.)
Mora triflex bushcrafter (This one is my favorite h
Ahti Metsa is a sexy knife for bushcrafting. (I believe a member on here sells them. Ragweed forge or somethin like that)
Condor Bushcrafter looks decent, but I've never tried it.
At the end of the day, a bushcraft knife is a knife you will use in the bush. You can spend as much or as little as you like, so long as the knife does the job you need it to do. I've used an old 8" carbon steel chef knife with a scandi grind before. It got the job done, and in that situation...it was a bushcraft knife
