Unfortunately I don't have any progress pictures, but this is my modified Cold Steel Trail Hawk. Out of the box it's actually pretty nice, especially for the price. I bought it as a lightweight hiking companion that serves the role of a hatchet. The poll is useful for putting in stakes and the edged face can process wood around the sizes you would use for a small cooking fire.
The stock version includes a set screw to secure the head to the handle. The swell at the end secures the head while being swung, but having a screw prevents handle replacement in the field, so I removed it.
The handle has a clear coat on it that is a little slick and probably would give you blisters if you used it long enough. I sanded it off and put a few coats of boiled linseed oil.
There is nothing wrong with the paint on the head but I wanted a more traditional "forged" look. I sanded off the paint and soaked the head for a few days in vinegar, periodically removing it and rubbing off the excess buildup.
Last I built a new sheath. Cold Steel offers a nylon version that only covers the edge, but in my experience the rivets tend to rust over time. I sketched a pattern on paper for fit and transferred it to 8 ounce leather. Once riveted, I treated it with Fiebing's black dye, carnauba wax, and neatsfoot oil.
Since this will be carried on the side of a pack it did not need a belt loop. I have found that the handles on tomahawks are too long to be comfortably carried like a traditional knife. I will be carrying this on a hike soon so we will see how the light waterproofing holds up.
