Build the fire chamber with firebrick, surround with whatever you like to look at. I have multiple plans for outdoor brick smokers from when I had planned to build one at our old house.
Anyone have or use one? Seems like a decent addition to a pack. I've seen pics where it was lashed to a make-shift handle to create a hatchet of sorts.
