Solutions for Permanently Securing Knots in Thick Leather Cords for Crafts.

Okay, I've looked into the user's need.

User Need Analysis: The user is working on a bag prototype and needs a way to make a knot in a really thick leather cord (used as a crossbody strap) permanent. The cord is too thick to sew neatly, which is a common finishing technique. This suggests a challenge in achieving a durable and aesthetically pleasing finish for a handcrafted item using thick, somewhat intractable materials.

Product/Service Opportunities:

  1. Product: Specialized Leather Cord Adhesive Kit

    • Description: A kit containing a high-strength, flexible adhesive specifically formulated for bonding leather, particularly porous or thick leather. It should dry clear or in a color that blends with common leather tones (e.g., black, brown). The kit could include a precision applicator tip for getting into the crevices of a knot, and perhaps a small bottle of leather cleaner/preparer to ensure optimal adhesion.
    • Expected Benefits: Creates a permanent, strong bond within the knot. Maintains some flexibility so the strap isn't overly stiff at the knot. Provides a cleaner finish than attempting to sew. Solves the "permanence" aspect directly.
    • Potential Revenue: Direct sales of the kit (e.g., $15-$25). Could be sold online, in craft stores, or leather supply shops.
  2. Product: Discreet Mechanical Cord Fasteners/Crimps for Leather

    • Description: Small, aesthetically pleasing metal (e.g., antique brass, gunmetal, silver finish) or durable polymer crimps/caps designed to be applied to the ends of the thick leather cord within or after the knot is tied. These would secure the loose ends and prevent the knot from unraveling. They might require a special plier (which could be sold separately or as part of a premium kit). Alternatively, screw-on end caps that pinch the leather.
    • Expected Benefits: Provides a very secure and permanent finish. Adds a professional, decorative element. More durable than adhesive alone in some cases. Prevents fraying or loosening of cord ends.
    • Potential Revenue: Sales of fastener packs (e.g., $8-$15 for a set of 4-8). Sales of application tools ($10-$20).
  3. Product: Knot Tightening & Setting Tool for Thick Cords

    • Description: A hand tool designed to provide leverage to pull knots in thick, stiff materials (like leather cord) extremely tight. It might have specialized jaws or grips that won't mar the leather. A more advanced version could incorporate a low-heat element (battery-powered) to gently "set" certain types of treated leather or to help cure specific adhesives faster when used in conjunction.
    • Expected Benefits: Allows users to achieve much tighter, more compact knots than possible by hand. Tighter knots are inherently more stable. Could reduce the reliance on adhesives or make them more effective by minimizing gaps.
    • Potential Revenue: Sales of the tool (e.g., $20-$40).
  4. Information Resource: "Mastering Thick Cord Finishes" Guide/Online Course

    • Description: A comprehensive digital guide (eBook or video series) demonstrating various techniques for finishing knots and ends on thick leather cords and similar materials. This would cover:
      • Specific knot types that are self-locking or easily secured.
      • Techniques for applying adhesives effectively within knots.
      • Methods for using mechanical fasteners.
      • Tips for skiving (thinning) leather cord ends slightly to make them less bulky for certain finishing techniques, if appropriate.
      • Alternative "no-knot" joining methods suitable for thick straps.
    • Expected Benefits: Empowers crafters with knowledge and skills. Solves the problem through technique rather than just a product. Appeals to DIYers who want to learn and improve their craft.
    • Potential Revenue: Sales of the digital guide ($10-$30) or enrollment in an online course ($49-$99). Could also be a lead magnet for selling related tools or supplies.

Overall Recommendation: The Specialized Leather Cord Adhesive Kit and the Discreet Mechanical Cord Fasteners seem to have the most direct market appeal and solve the user's stated problem effectively. The informational guide is also strong as it addresses a broader skill gap.

Exporting Result: The user is seeking a way to make a knot permanent in a thick leather cord for a bag strap, as it's too thick to sew.

Can anyone offer advice on how to make this knot permanent?

I’m prototyping a bag and decided to just use really thick leather cord as the cross body strap, and want to use that for the final product as well, but it’s too thick for me to make a tight
