I tried the Kubben for carving, didn't like it as it felt unbalanced to me and didn't allow for the range of grips i use when carving, ie chocking up the grip under the head for max control and fine cuts or holding the helve near the poll for more effective and powerful chopping cuts, i also found, like i do with the mini axe, that i was having to force the axe at times rather than letting the weight and natural arc of the grip do the work, which is asking for trouble.
If you get a wildlife or similar, you can not only use it for carving, but a whole host of things too, where the Kubben may be a bit limiting, but, of course, what's good for one is sometimes no good for someone else, so the Kubben may be ideal for you and what you want to do with it, try before you buy if you can and see how the Kubben & Wildlife suit your objectives.
