Interactive 3D Simulators

Four browser-based simulators covering the parts of knife making where the geometry and the timing are hardest to picture. Every one has a static reference fallback, so nothing breaks if your device cannot render 3D.

Educational models, not process simulationThese tools approximate real material behaviour well enough to teach the motion and the sequence. They are not finite-element models and they will not predict your result. Always follow the instructions supplied with your own equipment and the guidance of someone competent.

Performance notes

The 3D libraries load only when you open a simulator — the rest of the site never pulls them. Each scene is kept under roughly 20,000 triangles with textures capped at 2048 px, and the renderer drops resolution and shadows automatically if the frame rate falls below 30 fps for three seconds. Rendering pauses entirely when the tab is hidden.

  • On a phone, simulators open in their static reference view by default. There is a button to load the 3D version if you want it.
  • If WebGL is unavailable or the context is lost, the tool switches to the static view and keeps working — no blank canvas, no error.
  • If you have “reduce motion” set in your operating system, auto-rotation, spark particles and transitions are turned off.

Controls

  • Rotate: drag with the mouse or one finger.
  • Zoom: scroll wheel or a two-finger pinch.
  • Pan: disabled on purpose — it makes these small scenes disorienting.
  • Keyboard: every slider and button in the control panel is reachable with Tab, and the sliders respond to the arrow keys.
  • Reset: each tool has a reset that restores the starting state.
Working with hot metal, grinders and quench oil is genuinely dangerous. A simulator cannot burn you, and that is exactly the problem — do not let it stand in for real training, PPE and ventilation.
