Amazon has the Hardcore Hardware Australia MFE01 Tactical Tomahawk Black G-10, a tomahawk to make all other tomahawks cry in shame.
For starters, this tomahawk was jointly developed with the Australian Special Forces. That should be enough right there. The tomahawk was made for clawing, prying, breaking rock, smashing windows, "defeating" locks, and many, many other things. It's constructed with steel, a thick coating of teflon and a G10 handle.
