Couple of my favorite blades... Both from the Buck PakLite series.
The 140 is easy to find. Great ergonomics (at least for my hands). The thumb hole and jimping is thoughtfully placed. I carry and use this one a lot.
The 143 took me a while to track down. Handle is the same size, but the blade is about an inch longer and lacks the jimping on the spine. Buck made it as a walmart exclusive.
They also make the 135 Caper and now the 141 which they're calling a skinner but has a distinctly different shape. All made in the USA and a good value at less than $20.
