By far our go-to knife.
A perfectly-sized (4" closed, 7" open) Japanese-made Higo knife, with black handle and blue-paper steel blade. Hand-made (Japan) and hand-finished at our shop here in Dallas; no two will look the same. This is not a fancy knife, and our finishing process introduces cosmetic imperfections (so it won't look brand-spanking new!). It is a knife that gets the job done; cuts your apple or cigar, opens a box, slashes your pesky neighbor's tires.
The blue-paper steel produces a very sharp edge, easily honed as necessary. If you live in more humid areas or use it on fruit, a drop of oil (even olive oil) every once in a while won't hurt.
If you need a smaller Higo, look for Just Lefty, elsewhere on our shop. If brass is more your speed, look for Townes.
