Butterfly Trainer Knife

A balisong-style balance trainer — fully 3D-printed, unsharpened, and built for flipping practice rather than cutting. Four blade styles and three handle patterns went into the design, all mixed and matched here into one smooth, nearly frictionless trainer.

The blade and handle pivot on a simple filament pin instead of metal hardware — easy to reprint or reset if it ever wears down, and kinder to your fingers during drops. A satisfying fidget piece for practicing flips, or just for restless hands.

Choose your handle colour and your blade colour separately — mix them however you like.
