Brush Cutter Blade Patent Illustration

I have redesigned a brush-cutter blade and the new concept is sufficiently different from the existing patent that it warrants its own filing. The main novelty lies in the way I have changed the material composition, so the drawings must highlight those internal layers and interfaces clearly. I already have rough sketches that show dimensions and the location of each new material segment; they now need to be converted into fully compliant patent illustrations.

Your task is to translate my sketches into crisp, black-and-white line drawings that satisfy USPTO/WIPO standards—proper margins, reference numerals, uniform line weight, and hatching conventions for the various materials. Please preserve my proportions, but feel free to improve perspective, sectional views, and any exploded details that will make the composition changes unmistakable to an examiner.

Deliverables
• Complete set of patent-ready PDFs (one sheet per view, 300 dpi or vector).
• Editable source files in either AI, DWG, or a comparable standard CAD format.
• A brief key explaining material hatch patterns used, cross-referenced to my rough sketches.

Once we have the finished sheets, I will review and mark any minor revisions before final sign-off.
