Mora knives are great little cutters, but keep in mind that they are not all full tang. I believe the Mora 2000 is 3/4 tang, which should be plenty strong. The #1 I believe features a full 'rat tail' tang which again I think makes it pretty strong.
However there are some models with only a half tang or even what appears to be a 1/3 tang, and those I tend to worry a bit about when batoning or other rough use. Take a look at the x-ray here:
