Geode Cracker

thingiverse

This tool breaks open geodes with ease, thanks to its innovative design. The "geode guillotine" is crafted from 4mm laser-cut steel, ensuring precision and accuracy. Its blade inserts are intentionally rough-sharpened using an angle grinder - a deliberate choice to avoid creating razor-sharp edges that would simply dull on the geodes' hard surfaces. To use this remarkable tool, simply place your geode in the "jaws" of the guillotine, position a piece of wood on top, and give it a solid whack with a hammer. The result is almost instantaneous: with a satisfying pop, your geode bursts open.
