The Crystal Cutter is a tool added by Prodigy Tech. It can be used to break grown Energion Crystals without causing them to explode, costing 1 durability per stage harvested.
Right clicking an Energion Crystal will harvest a single stage, at the cost of 1 durability. If the Crystal was as its first stage, it will be instantly harvested instead.
The number of dropped Energion Crystal Seeds per harvested stage (except the first one) can be increased with Fortune.
