My DM took a small dent like that once when I battoned her through a knot in some wood, no biggie though, a little work on a steel and it was as good as new.
The SR77 does seem to dent easier than the steel on my MOD4 survival knife though as the only time I managed to dent that was when I was battoning through a nail that I didn't know was in the wood !!!! <img src="/ubbthreads/images/graemlins/doh.gif" alt="" />

I believe someone else on here is getting a MOD4 soon so maybe he can also compare it with some Yard blades !!! <img src="/ubbthreads/images/graemlins/grin.gif" alt="" />
