Nitram produces its charcoal using a unique process that maintains the wood's cell structure which increases the charcoal's durability and helps prevent breakage. Nitram charcoal doesn't break like willow or vine do, and feels much less brittle.
Because of its solid strength, the charcoal can be sharpened to a fine point with the Nitram Sharpening Block.
