Scissor Sharpening Advice

We sharpen all brands of hairdressing scissors including:

barber scissors, left-handed scissors and thinning scissors.

How Do You Service Hairdressing Scissors?

Hairdressing / barber scissors (including left-handed scissors) are taken apart and cleaned, so that we can examine each blade under magnification to identify any damage and assess the condition of the screw and washer.


If your previous sharpener used a bench grinder to replace the expensive convex edges with cheap bevelled edges - we will tell you whether or not, it would be possible to re-convex the hairdressing scissors back to how they were when you first purchased them.  

We hand sharpen hairdressing scissors using 5 types of wet and dry paper, 3 blocks of Japanese wet stones and 2 types of polishing leathers, this process creates a mirror finish, making the scissor blades razor sharp and smooth. 

All blade imperfections are removed with Japanese wet stones.  

The original manufacturers cutting angle is established so that we can ensure that the most minimal amount of metal is removed during the sharpening process.  We use a water-cooled machine to ensure scissors never over-heat.


For most scissors, we can source new screws, washers, scissor bumpers etc. If required, these parts are replaced free of charge.

We use 3 grades of Japanese wet stones to hand sharpen the inside of each blade.  Blades are continually assessed under magnification so that we can identify the areas (nicks and damage) which need the most work; this is a lengthy process which produces highly polished edges.

We hand sharpen the outside of each blade on the most advanced high precision equipment in the world, designed exclusively to sharpen professional hairdressing scissors (including left-handed scissors) to factory sharpness.  The outside edges are honed and highly polished, using premium products to produce smooth sharp scissors with a mirror finish.

If necessary, tips are adjusted and reshaped by hand. They are then rounded off, de-burred and polished.

It is imperative that the hairdressing scissors are re-tensioned and balanced.


Lubrication is applied and worked into the scissors.  We then test the cut along the length of the blades, using a specially made fabric.


Lastly, the tips are tested on clean hair. 


Be Cautious Of Mobile Scissor Sharpeners:

Be careful with mobile sharpeners, because many do not spend enough time servicing valuable hairdressing scissors and do not sharpen them on the correct machinery; the majority of scissor sharpening machines used, cannot re-convex hairdressing scissors/ left-handed scissors - we always put a convex edge on convex scissors.


Would you rather have someone spending 10 minutes sharpening your scissors, so that he can service as many scissors as possible in a day?




Would you rather someone take time and care with your scissors, spending between 20 - 30 minutes, professionally servicing them, removing the minimal amount of steel and guaranteeing that your scissors will cut like new?


Who do you think would provide the best service?


Many hairdressers have told us about their concerns, regarding mobile scissor sharpeners. They advised that not only was the noise incredibly loud (upsetting their clients), but they were unsure as to whether 10 minutes was enough to professionally service a pair of hairdressing scissors.  


THIS IS SHOCKING - we take between 20 - 30 minutes to professionally service one pair of hairdressing scissors/ left-handed hairdressing scissors!!    If a scissor sharpener is only spending 10 minutes on a pair of scissors - they are not servicing them correctly - ALARM BELLS SHOULD START RINGING


Be Cautious Of Inexperienced Scissor Sharpeners:

An inexperienced scissor sharpener or one without the correct equipment, could shorten the life of your hairdressing scissors/ left-handed hairdressing scissors or even destroy them. Many scissor sharpeners create bevel edges on convex scissors, remove excess amounts of metal, over-heat scissors and burn the tips. Unfortunately, there is hardly anyone in the UK. who has the correct equipment to sharpen convex hairdressing scissors.


Beware - Freepost Scissor Sharpening Envelopes

Be cautious of sharpening companies who send out free post envelopes - as there is no way you can track your parcel to ascertain whether or not your scissors reached the sharpening company ...... Sadly, many hairdressers have told us that their scissors went missing using freepost envelopes and this is why we would never use them.


Difference - Convex & Bevelled Hairdressing Scissors:


Most premium hair cutting scissors have convex edges, which have hand finished, razor sharp, highly sensitive edges and should be used for slide cutting, slice cutting, chipping and fan cuts. Convex hairdressing scissors will rapidly lose their sharp edges if used for blunt work or to cut thick sections of hair.

As previously advised, you must be extremely careful, when choosing someone to sharpen your expensive convex hairdressing scissors. 




Bevel edge hairdressing scissors are cheaper than convexed scissors, they have a machine cut face along the cutting edge, have tough edges and are very nick resistant.  They are good for blunt/point cutting and for bulk hair removal.


If you have a pair of convex hairdressing scissors, which have been previously poorly sharpened and now have bevel edges, dependant on the damage, we may be able to re-profile very slight bevel edges back to convex edges.  We can advise you once we receive your scissors.

Hairdressing scissors that have had heavy bevel edges applied to them, will not be able to be re-convexed, however, we will be able to drastically improve them and send them back cutting perfectly.


Repetitive Strain Injury

Preventing Repetitive Strain Injury:

RSI  - Repetitive Strain/Stress Injuries


Some hairdressers suffer from RSI because of reasons such as:  repetitive use of hands, poor posture and using poorly designed scissors.


Symptoms usually occur in the hand(s) and/or wrist(s) and can include:


Pain, aching, pins and needles, tingling, burning, loss of movement, swelling, numbness, loss of strength.


Early reporting of any of these symptoms is imperative; therefore if you suspect that you may be suffering from RSI, you must visit your doctor. 




It is crucial that your scissors are adjusted to the correct tension at all times.


Protect your hands from exertion by ensuring that your scissors are regularly serviced.


There are many scissors on the market which can assist with hand problems, do not use opposite handle hairdressing scissors and look for ergonomic designs. You do not have to use as much pressure when using convexed scissors as opposed to bevelled scissors.


You should be cutting with a straight wrist. Swivel scissors can assist in keeping your wrist straight because the rotating thumb ring means that the scissors can be moved into different positions, without awkward wrist movements. Offset scissors can also assist because this type of scissor does not force the thumb opposite the ring finger when closing and therefore allows the thumb more movement.


Check The Scissor Tension Everyday

If You Do Not Regularly Check The Tension On Your Hairdressing Scissors, They Will Not Cut Correctly:

Loose tension will cause the scissors to fold, pull hair, not cut at the tips or not cut correctly.

You should check the tension at the beginning of every day. 

Scissors have working parts, so will always loosen.  When scissor blades are too loose, the cutting edges of the blades will separate during the cutting action.  Properly adjusted blades hold their contact throughout the full cutting stroke.


Tight tension will cause the blades to grind against each other and could damage them. 

Both loose and tight tension, may cause user fatigue and could lead to hand problems.



The Correct Tension:


Whilst the scissors are closed, point the scissor tips towards the ceiling.


Choose the blade that houses the finger rest and open this blade to form a cross; then release this blade.


The scissors should not close, and depending on whether you are left or right handed the blade should stop between the:


1 and 2 o clock position   or   the 10 and 11 o clock position.  



Adjusting The Tension:


The blades must be closed when attempting to adjust tension.

More tension = clockwise            and           Less tension = anti-clockwise

Some long blades or scissors with a balance face insert may need to be tighter. No scissor should be looser.

Cleaning & Oiling Hairdressing Scissors:

You should clean and oil your scissors after every haircut, this will:

•        Make them cut better

•        Ensure longer lasting sharpness

•        Stop them corroding

•        Extend the cutting life of your scissors

•        Prevent build-up of debris and bacteria around the pivot area


Very carefully rinse your hairdressing scissors with warm water and carefully dry with a paper towel (do not rub the sharp edges with the paper towel), make sure you remove all hair and moisture; remember to pay particular attention to the screw/pivot area.

Use the tip of your oil dispenser to apply a thin line of good quality scissor oil along the scissor blades and apply a drop of oil to the screw/pivot area. The oil will help draw the hair out and will protect the screw by sealing out moisture.


If you are oiling scissors with a thumb tensioner; oil between the blades and on the back of the screw head.


If you are oiling scissors with a flat screw; oil between the blades and on the head.


Gently close and open them a few times to allow the lubricant to reach the washer.


Carefully remove excess oil and debris with a clean paper towel.


Dropping Hairdressing Scissors:

Dropping hairdressing scissors/ left handed hairdressing scissors is very likely to cause damage.  We can usually take out any nicks during the sharpening process. However, if the blades become very bent, this may render the scissors irreparable.

We can sharpen most dropped hairdressing scissors and return them cutting perfectly.


 Newly Sharpened Hair Scissors?

It is very important, that you do not loosen or tighten the screw, when we return your newly sharpened hair cutting scissors.  


The tension we set, is the correct tension for your scissors and this is how your scissors should feel when you re-tension them.


When you get your hairdressing scissors back, get used to the sharpness and the feel of them. If you were previously pressure cutting with your blunt scissors, your newly sharpened scissors will feel different; however, you must be extremely careful not to use the same pressure, because this would quickly dull the sharp edges.


Don’t lend your newly sharpened hairdressing scissors, other people don’t care for them as much as you and they may pressure cut, which will blunt the sharp edges. In addition, they may alter the scissor balance and make them feel different after one haircut.  


You should be vigilant with your hairdressing scissors/ left handed hairdressing scissors because fresh edges are far more fragile than run in scissors.
