Hello: Avgjoe35

Sharpening a scissors is like sharpening any other tool. A multi step process where each step and each process is required. Each step or process must be done correctly and accurately in order for the tool to once again perform as intended, like new and safely.

The best way to sharpen any scissors is to have the proper machinery to exactly duplicate the manufacturers beveled angle and maintain that angle all long the entire cutting surface.

Once that process is completed, there is the slight curve of the blades inwards towards each other to maintain the shearing action.

Next is the process to bevel down the outter ends of the tips enough and correctly so the shearing action of both blades continues to the end of the blades.

This step shortens the blades overall length but is required to allow the tips to come into contact with each other for full cutting length along the entire surface and sniping threads, etc.

Next is the center pivot point set at the correct tightness. To loose and there will not be shearing action. A center pivot point set too tight there will be too much opening & closing resistance. More hand pressure will be required to make cuts.

Some scissors, depending upon the size, cost & purpose have stops in the handles. These have to be ground down to allow the tips to meet. Less expensive common household scissors often do not have handle stops.

There is far more to sharpening a pair of scissors than often meets the eye to most people. Understandable of course. But to the sharpening pro each step in the process determines the final results. One error can ruin a quality scissors.

For most household common scissors, a workshop table top belt sander will do fine. Match the existing angle and follow it from inside edge to the tip. Grind on the belt lightly with the cutting edge facing upwards into the downwards moving belt.

Make several light passes to each blade. Just enough to remove the existing cutting surface and to create a new cutting surface. Use a 150 or 100 grit belt only.

Angle the outer ends of the blades inwards so the tips meet once again. All belt grinding processes must be done lightly to reduce the chances of metal overheating and surface bluing.

Less expensive scissors use a pop rivet to hold the scissors together. If there is excessive looseness at the pivot point, a common bench vise can be used to pinch or squeeze the pop rivot point together.

Do this process lightly and check often. Excessive center point tightness cannot be undone. This step done too tightly and the scissors can become next to useless.

Most expensive scissors and all fabric scissors, etc. use center pivot point threaded screws and or threaded screw and nut to hold the blades together. Some thread clockwise while others turn counter clockwise.

Thread stripping and head damage will result to the screw head if not turned correctly. To adjust the blade tensioning, the center point must be set correctly, so the screw and or screw and nut must be adjusted, so proceed with caution.

Blade inwards bent angle must also be correct. Not enough and the scissors will not shear properly. Too tight and the blades will grind together and distroy the cutting surfaces, bind up and the scissors can easily become useless.

Trail and Errors, Practice and Patience makes perfect.

I have such a pair. Well made commerical quality and certainly not a pair to attempt sharpening by a diy person.

If the scissors are still in good condition and only dull, have them sharpened professionally. Practice on a cheap common type scissor. You'll be gald you did.

Trail and Errors, Practice and Patience and a few distroyed tools later, makes perfect...

"So You Want Be A PROFESSIONAL SALON SHARPENER"

THIS MAY SAVE SOME OF YOU THOUSANDS OF DOLLARS!!!

1. I have been a sharpener for a very long time. I know what I'm talking about. I have many years of study, practice, experience, and education.
2. Do not buy a grinder to sharpen high quality salon shears!
3. Watch out for companies that lure you with a dream of a six figure income.
4. Have an attorney evaluate contracts
5. Have a private investigator do a background check on company or owner (not on-line) no matter how nice they seem. You may be quite surprised at what you find.
6. Use caution with companies that require you to meet what seems to be very easy sales quotas. They will can you if you don't meet them
7. Watch out for companies that require you to return all inventory and machinery upon termination even though you paid for it.
8. Salon Sharpening is hard work. It requires dedication, skill, experience, and superior sales ability to be successful.
9. Hair Stylists are not going to welcome you with open arms. Many, if not most, have had bad experiences with scissor sharpeners. They are very wary.
10. Watch out for companies that "harp on" a particular scissor radius or curvature on blade
11. You probably don't need to pay for a protected territory if you are an excellent sharpener. If you aren't, a protected territory will not do you any good. You will fail.
12. Some companies have an incredible professional sales presentation to get as much as $30,000 out of you. Use caution....If it looks and sounds to good to be true....it just may be.
13. Ask for 20 references, not 2 or 3, and see what they say.
They will have 3 or 4 of their pets that will tell you how great the company is and so on...
14. I would look for a company where you can purchase your machine outright, pay for your training, and purchase your shears.

good luck,

Sharp Matters
