Mora No 1 carbon steel.
I bought it to learn a few things on before "upgrading" to a Becker or something else more substantial, and then found it does everything I need in a knife. It goes along camping, hunting, fishing, you name it. Always sharp and always cuts effortlessly.
I have a Becker and a Bushcraft Black, I just don't find I need anything more substantial than that old Mora very often. I carries so effortlessly around my neck I rarely choose a larger knife to take its place.
