It seems you have moved beyond Winkler- which in general is a good thing. I have, or have had several Winkler Hawks and knives, never bought one- but they are not optimum for taking animals apart.
In that, most of the suggestions given make it clear that most are knife nerds (that’s ok), and not making suggestions on what actually takes animals apart the cleanest and easiest.
HalfFace Blades- they make about 1-2 knives with blade shapes that are decent, but the awfulness of their handles should obvious the moment someone who knows what they are doing grabs it. This goes for the vast majority of knives made regardless of price or reputation. There is a reason that butcher knives have largely reminded unchanged for hundreds of years, with the smooth, rounded handles and certain blade shapes without guards…
I worked in a butcher shop for a couple of seasons to learn, my average time to gut a deer start to finish is sub 20 seconds, and I field dress on average 30-40 bag game animals a year. I have used most of the super steels until about 5-10 years ago. I say that for an understanding of what I’m about to write….
I want nothing to do with any super steels. I want good basic carbon steel blades that are easy to sharpen in the field and last decently. A smooth, curved blade. Smooth handles, no finger grooves, no sharp edges, no guard- nothing to catch on inside an animal.
Simple, clean, purpose built.
The best overall knife I have used for breaking animals down in the field is the Canadian Belt Knife from Grohmann or other copies with no modifications to the blade or handle angle. Whereas a true butchers knife is phenomenal for skinning and slicing, utterly useless for anything pokie. The CBK’s unique blade shape and blade angle reticle to the handle makes it slice and skin excellently, and stab and poke well.
I would literally rather use the Cold Steel $15 version of the CBK than every “custom” knife thus far mentioned for actual field use on animals. Almost every person I have hunted has switched to the CBK after watching me use them, or using one themselves.
