My workhorses are a Buck Vanguard and a no-name three-blade pocket knife that I call by a pet name.
Any other knives that I use are either special gifts from dear people, or specialized (like filet knives) and backups for actual butchering.
The Vanguard (I own three) is commonly available, and a comparable folder, with high carbon steel blades, can be found from Schrade or Boker. The walking-about-the-woods-with-a-friend feeling can only be had with a gift knife from a kindred spirit.
My pocket knife, before rescaling. This knife gets first dibs on a fresh game animal.
Buck Vanguard for heavy work. I have two rubber-gripped and one rosewood.
Gift from a friend... priceless! (Click it. It gets bigger.)
