The Dark Matter Axe is a Dark Matter Tool that has unlimited durability.
The Dark Matter Axe cuts faster than a Diamond Axe. In addition, by default pressing "V" to charge (this key can be changed via the controls menu), then right-clicking with the axe equipped, you can clear all logs and leaf blocks nearby, with all drops being sent directly on the player. (Fuel is required for this function; see below.) This is useful for quickly clearing large trees or forests.
Fuel Usage and Charge
The right-click ability requires fuel. It can use any item that EE classifies as "Fuel", such as coal, glowstone, a charged Klein Star, etc. The amount of fuel used is dependent on the number of blocks broken, similar to all other EE block-breaking tools. The length of the right-click ability is dependent on the EMC of the fuel used. All Dark Matter Tools have two charge levels, increasing the breaking speed of the tool by a factor of the charge.
