What spike? A traditional tomahawk was a gen purp survival tool You could fight with it, build a campsite with it, dress game, etc. Spiked tomahawks weren't so common, though you will find them here and there. They were more of a special purpose deal.

When I am hunting, I will often carry a S&W hatchet/knife combo. It is not the highest quality, but it works, and works well for me. I used it to field dress an elk, and I keep the edges on both very sharp. The hatchet will dress pole ends quite effectively. I wouldn't use it to go cutting up old growth windfalls for firewood, but it'd sure help trimming lodgepoles and such. It is fantastic for kindling.

Other times, I might carry a small wooden handled hatchet along with an axe if I am doing timber patrol.
