As the name suggests, crystals in this form assist with keeping one sharp and on point. The BFF crystal for anyone who needs to stay focused, so they make great study-buddies.
These are also a fantastic shape for manifestation. Write down a desire, manifestation or mantra on a piece of paper, fold it, and place your crystal point directly on top. This action directs all the energy from the intention, radiating it upward and outward.
