The 710 is a great example of a big knife that carries small. In that category I don't think it can be beat.
Thin and easy to carry with no trade off in strength. All the one's I've had were very smooth. However, as with any production knife there will be variances but AXIS knives tend to be smoother in general then most or nothing slight adjustment of the pivot can't improve to ones liking.
It's no accident the 710 has stood the test of time and still around and desired after more then 15 years. One of BM's standouts that I have no problem recommending.
All the best!
