Howdy,
Well...if you were to say you wanted pics of "lockbacks and trappers", you would be asking for two reasonably specific patterns. Although "lockback", being a lock style, rather than a specific pattern, does tend to include various blade styles.
If you were to say you wanted pictures of "traditional knives", that would include many other patterns, including lockbacks, trappers, stockman, teardrop jack, serpentine jack, dogleg jack, melon tester, sowbelly, sway back jack, whittler, copperhead, canoe, congress, peanut, sodbuster, toothpick, doctor, muskrat, surveyor, cattleman, and others.
AG Russell is a paid BF dealer member, which allows us to reference them in our posts. They have a reasonably complete glossary of knife terms on their web site

You will find a wide variety of traditional knife patterns illustrated in this thread:
