How to Model a Knife Blade in Fusion 360

Using Fusion 360 CAD to sketch and model a basic knife blade for a fixed-blade knife! This tutorial shows basic sketching as well as sketch tricks to switch from sketching a line to an arc, then adding dimensions the sketch, then extruding to a 3D solid model of the basic knife blade shape.

After the basic profile of the knife blade has been extruded, we sketch a line to use as a sweep cut to add the bevel to the knife blade.

Fusion 360 Commands used:

  • Sketch Constraints
  • Symmetric Extrude
  • Plane along Path
  • Sketch Project
  • Slice View
  • Sweep and Loft with Guide Rails
