How does that DT-12 compare ?
Before I answer your question, I wanna' preface my answer by saying that I have very limited time (*for my standards) with both.
That being posted, both seem to be good "choppers", which I assume is their intended purpose. The Kodiak has the advantage in terms of heft. It's a damned wood bomb. The DT-12, as a chopper, has the advantage in terms of the full-flat. Because of each of their inherent benefits, both bite pretty deep when it comes to chopping.
In my travels at remote Farms and Ranches, here in South Texas, I'm usually able to grab from established woodpiles of very large and (*usually) aged/very hard pieces of wood. So, I don't really have much use for a "chopper", and tend to use my big blades for splitting/reducing. In that role, both are about an "7" or "8" of "10". (*I have other blades that perform better for batoning) When it comes to splitting, the Kodiak has the advantage of the saber grind. (*albeit shallow for the height of the blade) The DT-12 has the advantage of "span" because of the blade length.
If you could live with a knife of the size of either of these, both would be great "camp" blades if you were wanting to abandon your camp hatchet or Sportsman's axe. Both will grenade wood all day, and then go straight to cutting rope/cord, prepping protein/veggies for the fire (*If, for some reason, you didn't have a trusty folder in your pocket), and sleeping under your pillow for wild animals of the two or four-legged variety. Neither is gonna' filet fish like a chef's knife, but other than that should handle just about anything you can throw at 'em.
Happy hunting...
