ADJUSTING A SLOTTED TENSION SCREW

  1. Hold hair shear in closed position, firmly in left hand (or right hand if you are left-handed), place blades of hair shear on a table or solid surface.
  2. Select a screwdriver that fits closely in the slot in the pivot screw.
  3. Hold screwdriver firmly in right hand (or left if left-handed)
  4. Bear down on the screw so you will not slip and burr the screw head.
  5. Turn the screw head. Turn the screw about ¼ turn clockwise and check tension.
  6. Continue to turn in ¼ increments until there is the amount of tension you prefer between the blades when the hair shear is opened and closed (usually one shear blade should drop about 1/3 closed and stop).
  7. If the screw will not turn, try loosening the screw first (counterclockwise) then try to tighten.

If you still can not get your hair shear adjusted right. You can send it in to Custom Sharpening with a note attached telling us how you would like it adjusted.

ADJUSTING HAIR SHEARS

IT IS IMPORTANT TO KEEP THE HAIR SHEAR TENSION PROPERLY ADJUSTED!

Hair Shears feel better when the blade tension is properly set. They also cut more efficiently when the blade tension is sufficiently pressing the cutting edges against one another such that you can feel a slight resistance when you close the scissors without cutting anything.

You can also judge if the tension is correct by holding one handle of the hair shear, and with the shear open, dropping the upper handle. The blades should fall about half way closed and then stop. This will vary depending on the type of shear. Higher quality precision hair shears may drop only a quarter of the way closed before the blades stop yet they will still have a very light and smooth action. Ultimately the tension should be adjusted to your preference.
