Folding knives are carried and used every day by people at home, work and on the job. Designed around a pivot that connects the knife blade to the handle, folding knives are made with various types of metals and handles. During normal everyday use, knife handles can become loose. Correcting the issue requires tightening the knife so that more tension is applied to the blade. The blade should open smoothly, and there should be little to no side movement when locked open.

Skill level:

Things you need

  • Screwdriver with Allen head or Torx bit
  • Knife oil

  1. 1

    Hold the folding knife by the handle with one hand and carefully open the blade with the other hand. Close and open the blade several times as you observe the looseness of the blade.

  2. 2

    Select a screwdriver with an Allen head or Torx screw bit. Match the size of the bit to the pivot screw so that the screw will not be marred or damaged as it is tightened.

  3. 3

    Insert the tip of the screwdriver into the pivot screw. Turn the handle of the screwdriver slightly to the right to begin tightening. Only make small incremental adjustments at a time. Open the blade of the knife to check the tension.

  4. 4

    Continue making small incremental adjustments to the pivot screw until the blade is held securely in place when opened and is not too loose or too difficult to open.

  5. 5

    Apply a small amount of knife oil to either side of the blade at the pivot point. Work the oil down into the washers at the pivot point by opening and closing the blade several times.
