A couple of things.
If you're used to modern tacticals, realize that traditional knives carry a bit bigger and heavier in your pocket because they rest at the bottom, instead of clipped to the top. You may want to consider a mini-trapper instead of a full-sized trapper. Same thing, smaller package.
Also, being used to modern knives, you've acquainted with stainless super steels. Because of this, I would add to the chorus of those recommending Queen. Their D2 is fantastic, resists rust and holds a sharp edge for a very long time. In the steels you mentioned, Buck's 420HC is the next most wear resistant (due to Paul Bo's heat treat, not the steel itself), then Case CV which is like 1085 with Chromium and Vanadium, then Case True Sharp which is like 420. I don't care for True Sharp in a user knife since I like to really thin my knives out and give them secondary bevels on a Sharpmaker set to 15 degrees.
Queen Amber Carved Stag Bone is really beautiful and durable--I'd steer you towards that unless something else calls out to you. Be warned that most Queen D2 comes dull as a butter knife. If you have the tools to sharpen it, the knife will be a fantastic user for you. If you don't, you'll be cursing Queen. Queen also makes knives with 1095 and those have an exceptional heat treat and come sharp out of the box.
