If I could only carry one knife it would be the bottom one, a Puma that my father gave me in 1992 for a bighorn archery hunt.
I have used it on every animal since then
The top one is a Marttiini that a Finnish friend sent me when he moved back.
The hatchet used to stay in my pack for cutting brush, etc , but I have also used it for sternums on moose and other such duties.
It has since been replaced by a Kukri that a friend made for me.
The Leatherman is always on my belt , regardless of where I am - unless of course, I am wearing a Tux! LOL
