How Do You Sharpen Dog Grooming Scissors?

Scissor Sharpening

Dog grooming scissors are cleaned before being examined under magnification to identify any damage.

We then establish the cutting angle used by the original manufacturer, to ensure that a minimal amount of metal is removed during the scissor sharpening process.

Most dog grooming scissors that we receive have blade imperfections such as nicks and damage. These imperfections are removed with honing stones.

If blades are slightly bent, we will advise you, as to whether or not they can be sharpened.  Only a scissor sharpener with experience can tell if slightly bent scissors can undergo a scissor sharpening process. Some slightly bent scissors cut perfectly well.  

 

There are very few dog grooming scissors on the market that can be re-shaped, this is because they are made from non-pliable hard brittle steel.

 

The condition of the centre screw/ thumb tensioner is assessed and if required, screws, washers, finger rests and bump stops will be replaced.

 

The initial tension is set.

 

Tips are adjusted and re-shaped by hand.

 

They are then rounded off and deburred to ensure they are safe of use.

 

Dog grooming scissors are then sharpened on scissor sharpening equipment designed exclusively to sharpen professional scissors to factory sharpness.  

 

The blades undergo a polishing process to produce even sharper edges.

 

Dog grooming scissors are then put in an ultrasonic cleaning tank, which generates acoustic shock energy to remove even the most ingrained dirt, particularly from parts that traditional cleaning methods can’t reach.

The scissors are again, tensioned and balanced.

Lubrication is applied and worked into the scissors.      

The cut along the length of the blades is tested, using a specially made scissor fabric.

Tips are then tested on clean hair.

Premium dog grooming scissors take longer to sharpen and are sharpened differently  - The differences are highlighted

Premium dog grooming scissors have to be taken apart.

Blades are cleaned before being examined under magnification to identify any damage.

We then establish the cutting angle used by the original manufacturer, to ensure that a minimal amount of metal is removed during the scissor sharpening process.

Most dog grooming scissors that we receive have blade imperfections such as nicks and damage. These imperfections are removed with Japanese wet stones.

If the scissors are bent, we will assess whether or not the scissors can be reshaped. We can re-shape some high quality (premium) scissors due to the temper of the steel, which is soft and pliable.

The condition of the centre screw/ thumb tensioner is assessed and if required, screws, washers, finger rests and bump stops will be replaced.

The inside of each blade is sharpened by hand, using 2 grades of Japanese wet stones. The inside of the blade is continually assessed using a magnifying glass to identify the areas which need the most work, to ensure that minimal metal is removed.  This is a lengthy process which produces highly polished edges.

The outside of each blade is sharpened on scissor sharpening equipment, designed exclusively to sharpen professional premium scissors to factory sharpness.  

The edges are honed and highly polished using premium products, to produce smooth sharp scissors with a mirror finish.

Scissors are put in an ultrasonic cleaning tank, which generates acoustic shock energy to remove even the most ingrained dirt, particularly from parts that traditional cleaning methods cannot reach.

Ok – we have no medical knowledge about RSI (repetitive strain injury)  - But if you have any pain such as : aching, pins and needles, tingling, burning, loss of movement, swelling, numbness, loss of strength – you must visit a doctor for advice.

 

Using both dog clippers and scissors can put your hand and wrist in unnatural positions. If you feel any pain make sure you visit a doctor and make the necessary ergonomic changes. 

 

If you think you have RSI (Repetitive Strain Injury), it’s important not to ignore it. Sometimes, RSI has an underlying cause, such as carpal tunnel syndrome, which causes pain in your hand and wrist. If you don’t get it treated, you may end up with long-term (chronic) pain and find some day-to-day activities difficult.

 

You may not have any physical signs such as swelling, even though your hand or arm feels painful. The pain may get worse with time if you don’t get any treatment. Your pain may increase or start affecting you more frequently.

 

RSI  - Repetitive Strain Injury – Dog Groomers

 

Some dog groomers suffer from RSI because of reasons such as: repetitive use of hands, the wrist being placed in unnatural positions, poor posture and using poorly designed equipment.

 

 

RSI - Prevention

 

It is crucial that your scissors are adjusted to the correct tension at all times – to prevent you from using more pressure to make them cut - make sure they are regularly serviced.

 

Check how you are holding your scissors; you should be cutting with a straight wrist.

 

Many dog grooming scissors are not ergonomic so, therefore, place the hand in an unnatural position. 

 

There are many dog grooming scissors on the market which can assist with hand problems, do not choose opposite handle scissors and look for ergonomic designs. 

As previously advised, 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.

Newer dog clippers are being ergonomically designed and these dog clippers are not as heavy as old designs and feel easier to hold.  But remember – if you ever feel that your hand or wrist is being placed in an unnatural position, you will need to make adjustments.  

Dog Grooming Scissors - Advice

Always keep your scissors closed (except when in use) because you risk chipping the edges.

 

Cut only hair with your scissors and endeavour to wash dirty hair before cutting.  

 

Clean, wet hair causes the least stress on your scissors.

 

When you get your sharpened scissors back, don’t lend them;  other people don’t care for them as much as you and they may pressure cut, which will blunt the edges.  

 

 

HANDLING

 

Newly sharpened dog grooming scissors will have extremely sharp edges and must be treated with care. The fresh edges are easier to damage than run in scissors. Please don’t apply pressure when closing the scissors, you could catch or damage the edges.  Take extra care at first, get used to the sharpness and the feel of them.  You may have been previously pressure cutting with your blunt scissors, however, if you used the same pressure with newly sharpened scissors, you will quickly dull the edges.

SEIZED CENTRE SCREW

On occasions, we receive dog grooming scissors with a seized centre screw.  Upon receipt, we will be able to advise whether or not the scissors will be able to undergo a scissor sharpening process.  

STORAGE

Store your dog grooming scissors in a place where you cannot damage the edges (leather sheaf, pouch) and be mindful that moisture trapped in a plastic case will corrode them.

Check the tension on your dog grooming scissors everyday

It is critical that your scissors stay in the correct adjustment - if you don’t regularly check the adjustment they will not cut correctly.  

 

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

 

Loose tension will cause the dog grooming scissors to fold hair at the tips; consequently, you will use extra pressure to solve this problem.

 

Tight tension will cause the blades to grind against each other; consequently, you will have to use more pressure to open and close the scissors.

 

Both loose and tight tension will damage the sharp edges, cause user fatigue and could lead to hand problems.

 

Your scissors with perform best, if you adhere to the tension we set after we have sharpened your scissors.  

 

 

 

The correct tension for your dog grooming scissors:

 

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.

 

If in any doubt, please do not hesitate to phone us.

SCISSOR TENSION

 

Do not loosen or tighten the screw when we return your newly sharpened scissors. Tightening will grind the blades together destroying the sharp edges that we put on your scissors.  Setting the scissors too loose will fold the hair at the tips, causing you to use extra pressure. which will dull the blades faster and may give you hand problems.

 

The tension we set up is correct and should be adhered to. 

 

If you need looser scissors because you have hand troubles, there are ergonomic dog grooming scissors on the market which can help.

 

Dropping Your Dog Grooming Scissors

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

 

We can re-shape some high quality (premium) scissors due to the temper of the steel, which is soft and pliable. However, many standard dog grooming scissors cannot be re-shaped, because they are made of hard brittle steel and they would more than likely snap if pressure was applied.

 

Only a sharpener with experience can tell if slightly bent scissors can be sharpened.  Some slightly bent scissors will cut perfectly well. Upon receipt, we will advise whether or not your bent scissors would be able to undergo a sharpening process.

Cleaning & Oiling Your Scissors

Daily cleaning and oiling will enhance the performance and extend the cutting life of your scissors.

 

Scissors are not meant to be used dry (without oil) - oil them every day with a good quality scissor oil, this will make them cut better, stop them corroding and they will last longer.

 

When the blades are covered with hair and moisture, rust can occur.

 

Carefully remove all hair and moisture with a paper towel, put one drop of oil on either side of the screw and then apply a thin line of oil along the scissor blades with the tip of your oil dispenser.  

 

Gently open and close your dog grooming scissors a few times, then very carefully remove excess oil and debris with a clean paper towel.  

Make sure your scissors are clean and oiled, before storing overnight. Store your scissors in a place where you cannot damage the edges (leather sheaf, pouch) and be mindful that moisture trapped in a plastic case will corrode them.

The Difference Between Convex and Bevel Scissors

The difference between convex and standard dog grooming scissors (usually bevel edges - eg Roseline):

CONVEX EDGES

Convex scissor blades have hand finished, razor sharp edges, which should be used for finishing on clean hair.  

The edges are highly sensitive and dropping them can result in more damage than if you were using bevel scissors.

Be careful when choosing someone to sharpen your expensive convex scissors - you must check if the sharpener has the expertise and correct equipment to sharpen a pair of premium convex scissors.

When attempting to sharpen convex scissors, many sharpeners do so by grinding the scissor blades resulting in cheap, thick bevel edges. If a bevel edge is applied to a pair of convex scissors, this could alter the angle of the blade, resulting in severe damage.  

If you have a pair of convex scissors which have been previously poorly sharpened and now have bevel edges, we may be able to re-profile the edges back to convex blades.  Our scissor sharpening experts will determine whether or not this is possible.  

BEVEL EDGES

Bevel edges have thicker edges, they are robust and great for general purpose cutting and bulk hair removal.  

Bevel scissors have the toughest edges which are also very nick resistant.

Most dog grooming scissors have bevel edges, however, convex scissors (which are usually found in the hairdressing industry) are starting to emerge in the dog grooming industry.
