@manitou, The knife you have is better than no knife, and often that may be smaller than you might have intended. For sure a 3 inch blade will suffice as you have described. I too have used 3 inch as well as more or less on various game.
A couple stories to illustrate that point. A couple we were friends with told a story on themselves. They ran a safari business in Kenya, and those were well organized, had particular people assigned to logistics, and they always had what was needed for formal safaris. But on one trip they took to fill their own meat larder, they found themselves a little short on knives. Among them they had a Swiss Army knife and a bread knife to deal with antelope, impala, and possibly other game that would need to be cleaned and prepared for transport. A little embarrassing. Probably some of their staff was with them and they would have had pangas (similar to a machete). They got the job done anyway.
For years I worked as a biologist at a secure facility. The limit on the knife blade I could carry on the site was 2 inches. Over time I performed necropsies on several adult buck mule deer with that 2-inch knife. Those included fully gutting and skinning the dead deer, then poking through innards and sometimes dissecting wounds from antlers, etc.. While I didn't quarter them up, that tiny blade would have gotten the job done. To further illustrate that point, after it became legal in that state to pick up road kill, a fellow in a big old jeep plowed into a couple spike elk right in front of me on a snowy evening commute. Not to be one to pass up an opportunity I claimed one and another guy claimed the other. The guy who hit them didn't want one. The other salvagee and I, between us, had a Leatherman and my 2 inch blade. We dressed both elk and halved them so we could load them into our respective vehicles. It wasn't much, but it was what we had.
