After checking with a friend who's a blade fanatic, I think you should take a look at: http://www.2hawks.net/index.html

They make custom knives and tomahawks. The person running the business now is an apprentice of the gentleman that had built the reputation of the "Two Hawks" brand. The owner passed away, but, the apprentice continues to make the traditional models along with some more "modern" (if tomahawks can be modern) models.

He makes a model called "The Woodsman" which is a lightweight model for backpacking.
