3D Printing

Watch a digital design rise into a real object, layer by molten layer.

Ideal for those who enjoy tinkering with machines that sometimes break down..

Knife Making

Make knives by stock removal — grinding, heat-treating, and handling steel into a finished blade.

Grind, heat-treat, and handle a blade from a bar of steel — a real knife you made yourself.

Which is right for you?

Choose 3D Printing if…

  • Leveling the bed and tuning a Z-offset feels like a puzzle, not a chore.
  • You want a bracket or hook that holds real weight in your hand.
  • Diagnosing why a print warped is half the fun for you.

Choose Knife Making if…

  • A genuinely useful, beautiful object at the end — and you made every part of it.
  • Low barrier to start: files, a vise, and a bar of steel are enough.
  • Deeply tactile, physical making that gets you off screens entirely.

Before you commit

3D Printing

  • A print detaching into a spaghetti tangle would ruin your evening.
  • You expect the first attempt to work without any fiddling.
  • You would rather not live inside slicer settings and nozzle clogs.

Knife Making

  • Hot, dusty, sparky work that needs a garage, shed, or dedicated space.
  • Heat-treating is its own skill (or a send-out cost) and makes or breaks the blade.
  • Hand-grinding is slow; a belt grinder is the upgrade everyone eventually wants.
