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.

HOW TO INSERT A BUMPER

  1. Remove the old glue that could be in the hole and around the edges. You can use a toothpick or pipe-cleaning tool to do this.
  2. Take the bumper that fits your shear and insert it into the hole.
  3. Attach a very small drop of Super Glue into the hole where the top of the bumper makes contact with the metal of the finger ring.
  4. Hold it in place until set.
  5. If you use the bumper with a tail, trim off the excess tail- otherwise skip this step.
  6. You are now all set to go back to work.

HOW TO KEEP YOUR HAIR SHEARS LUBRICATED!

Proper lubrication keeps the metal parts that contact and slide against one another from wearing out prematurely while it gives the hair shear that smooth effortless feeling you liked so much when the shear was new. This is because lubrication reduces the friction and drag between the contacting surfaces. Lubrication also aids in preventing rust and corrosion of the metal. YOU DO NOT NEED TO LUBRICATE THE NEW RIDELESS BALL BEARING PIVOT HAIR SHEARS.

  1. Put a drop of light oil or silicone lubricant between the blades at the “ride” (the crescent shaped area behind the pivot screw near the handles) and wipe the excess off with a cloth.
  2. You may then wipe down the shear blades with the cloth (VERY CAREFULLY HAIR SHEARS ARE RAZOR SHARP!) to coat the blades with a thin film of lubricant.
  3. Do this at least once a week but preferably at the end of each day.

AN AEROSOL SILICONE LUBRICANT has the advantage of blowing out hair and debris from the pivot area of your hair shears as you spray it on.

Silicones are preferable to oils as hair does not stick to the dry silicone film as it does to oil.
