How to Replace or Mod 91mm Swiss Army Knife Scales Using Glue?

Replacing or modifying 91mm Swiss Army Knife scales using glue can be a delicate process, but it's possible with the right materials and careful handling. Here's a step-by-step guide to help you through the process:

Materials Needed:

  1. Replacement Scales: You'll need new scales that are compatible with your 91mm Swiss Army Knife model. These scales should come with pre-drilled holes for the pins.

  2. Epoxy or Super Glue: You can use epoxy adhesive or super glue for this project. Epoxy tends to be more durable and provides a stronger bond, but super glue can work if used correctly.

  3. Pins: You'll need metal pins or brass rivets to secure the scales to the knife.

  4. Clamps or Rubber Bands: These will be used to hold the scales in place while the glue dries.

  5. Sandpaper: To sand the edges of the scales for a smooth finish.

  6. Masking Tape: To protect the knife's blades and tools during the process.

Step-by-Step Guide:

  1. Prepare Your Workspace: Find a clean, well-ventilated workspace with enough room to lay out your tools and the knife. Ensure you have all the necessary materials within reach.

  2. Open the Knife: Carefully open all the blades and tools on your 91mm Swiss Army Knife. This is important to access the attachment points and to prevent damage to the blades.

  3. Remove the Old Scales:

    a. If you're replacing existing scales, use a small screwdriver or similar tool to carefully pry them off. Be gentle to avoid damaging the knife's body.

    b. If you're starting with a knife that doesn't have scales, proceed to the next step.

  4. Prepare the Knife: Ensure that the knife's body is clean and free from any adhesive residue or debris from the old scales.

  5. Prepare the New Scales:

    a. If you're modifying existing scales, make any necessary adjustments or cuts to achieve your desired shape or design.

    b. If you're replacing scales, ensure they are the correct size and shape for your knife model.

  6. Apply Glue:

    a. Apply a small amount of epoxy adhesive or super glue to the knife's body where the scales will attach. Be careful not to use too much, as excess glue can squeeze out and create a messy finish.

    b. Apply a thin, even layer of glue to the back of the scales.

  7. Attach the Scales: Carefully align the scales with the knife's body and press them firmly into place. Ensure that the holes in the scales align with the holes in the knife for the pins.

  8. Insert Pins: Insert the metal pins or brass rivets through the holes in the scales and the knife's body.

  9. Secure the Scales: Use clamps or tightly wrap rubber bands around the knife to hold the scales in place while the glue dries. Follow the adhesive manufacturer's recommended drying time.

  10. Trim Excess Material: After the glue has dried, trim any excess material from the pins using a file or sandpaper.

  11. Final Touches: Sand the edges of the scales for a smooth finish. You can also apply a finish or polish for added protection and aesthetics.

  12. Inspect and Test: Double-check that the scales are securely attached, and there's no play in the knife. Ensure that all the blades and tools open and close smoothly.

With these steps, you should be able to replace or modify the scales on your 91mm Swiss Army Knife using glue. Be patient and precise during the process to achieve the best results.
