Start defining who your blade is. Think of this like building a character - it has a name, a personality, a look, and a way it fights. The more thought you put in here, the clearer your design direction will be when you start drawing.

This is where your idea becomes a design. The goal is to translate your theme into actual geometry - specific shapes, silhouettes, edges, and forms. Think beyond color and decals. Anyone can paint something to look like an ocean. But can you design a blade that moves like one?

Before you write your analysis, use the demo below to build an intuition for angular momentum. Interact with it, then answer the questions that follow.

Minimum one top view and one side view. These are not CAD drawings but must be more than rough thumbnails - proportion, blade geometry, and overall shape must be clearly readable. Annotate with approximate dimensions. Click to add files or drag and drop. Add captions to identify each view.

Identify at least 3 manufacturing processes you plan to use. For each, list which component(s) it will produce and briefly explain why that process is the right choice. Note: two variations of the same process (e.g. two different print settings) count as one.

The blade contact rule has one purpose: your IDEA-Blade must actually fight. Any surface that makes contact with an opponent's IDEA-Blade must be capable of transferring force into it - disrupting its spin, knocking it off-balance, or driving it toward the boundary. An edge that simply lets an opponent slide past without meaningful force exchange is not legal. Review the contact rule in the rulebook before answering.
