Why Does the Pivot Pin Become Loose?

The pivot pin of a stacking leather knife may become loose over time for several reasons:

Frequent Usage

The pin is subjected to pressure from frequent usage, which causes wear and tear.

Environmental Exposure

Moisture, humidity, or temperature fluctuations may impact the leather and metal components.

Improper Maintenance

The stability of the pin may be jeopardized if regular maintenance is neglected or if earlier adjustments are overtightened.

Finding the underlying reason enables you to fix the problem correctly.

Evaluate the Damage

Start by taking a close look at the knife. Check to see if the pivot pin is only loose or irreparably broken. If it is cracked, bent, or very worn, it could need to be replaced.

Disassemble the Knife

You must partly disassemble the knife to repair the pivot pin:

Any fittings or screws keeping the handle together should be removed.
Remove the blade from the handle, so the pivot pin and related parts are visible.
Take care during disassembling to prevent breaking the leather handle or misplacing minor pieces.

Secure the Knife in a Vice

Place the knife handle in a clamp or vice to ensure the pivot pin is accessible. Use cushioning to prevent pressure imprints on the leather. At this step, the knife is stabilized, enabling accurate adjustments.

Tighten the Pivot Pin

Use a tiny screwdriver or flat punch to pound the pivot pin gently with a hammer. Apply equal pressure to prevent overtightening, which might limit blade movement. Periodically check the pin's stability by rotating the blade.

Strengthen with Adhesive

If the pivot pin is still a little loose, put a tiny bit of leather glue or epoxy around the base. This will prevent the pin from loosening in the future and help secure it. Before putting the knife back together, let the glue dry as directed by the manufacturer. 

Replace the Pivot Pin (If Necessary)

Replace the pivot pin completely if tightening and adhesive reinforcement are insufficient to fix the problem:

Using a punch tool, carefully remove the old pin.
Make sure that the new pin fits tightly into the assigned hole.
Secure it by gently tapping it into position. 

Reassembling and Adding Finishes

After the pivot pin is in place, put the knife back together:

• Reattach the handle and blade parts.
• To ensure a solid but not too tight grip, tighten screws or fittings.
• Verify the knife's operation to ensure the blade pivots smoothly and steadily.
• Use fine-grit sandpaper to soften any sharp edges surrounding the pivot area for a polished appearance.
