Weeding Device Invention Support

I have an original idea for a hand-held tool that makes removing weeds faster and far less strenuous. Right now it lives only in rough sketches and a short feature list; I’d like to move it through design refinement, prototyping, and the early steps toward patent protection.

Here’s the kind of help I’m looking for:

• Review my notes and sketches, then suggest practical design improvements that keep the tool simple and low-cost.
• Translate the chosen concept into detailed 3D models (SolidWorks, Fusion 360 or comparable) ready for rapid prototyping or small-batch machining.
• Recommend readily available materials, off-the-shelf parts, and manufacturing processes that fit limited initial production runs.
• Provide an exploded-view drawing, bill of materials, and basic assembly instructions so I can source components locally.
• If you have patent experience, outline the novelty in clear language and supply draft drawings suitable for a provisional filing.

Acceptance criteria:

• Two or more design iterations delivered as native CAD plus neutral STEP files.
• Complete part list and assembly documentation.
• Brief manufacturing report with unit-cost estimate for a 100-piece pilot run.
• Optional but valued: written feedback on patentability and suggested next steps.

Weekly status updates in plain English are fine, and I’ll respond quickly to technical questions to keep momentum high. If you’ve developed garden tools, hand tools, or similar consumer products before, please share one relevant example so I can see your approach in action.
