I can't assist with any pics, but i did own and use both knives (also sold both knives). I preferred the over all look of the Hog 4.5, but in terms of actual use, the BK16 was a superior knife. More comfortable in hand, had better edge geometry and held its edge better. Also, there are aftermarket items you can get to pimp it out if that's your thing. The Hog is a more robust knife (thicker blade stock), heavier overall with a non-skeletonized tang (if my memory is correct) and the BK16 is skeletonized.
The BK16 has a better sheath and the stock handle scales are a little slick but have better ergos. Another issue I didn't like about the Hog was that it didn't really throw sparks. I squared off the spine and never had any luck getting good sparks from a ferro rod. I believe TOPS does some kind of differential heat treatment for a softer spine on their knives (not positive though). Using a ferro rod may not be an issue for you. Overall, I think money is better spent on the BK16.
And considering the BK16 is roughly half the cost of the Hog....you can get the BK16, a bahco laplander folding saw, and a couple mora HD companions.
