Can I  sharpen my own clipper blades?

No (Not Usually!)

– Sharpening clipper blades is not like sharpening Knives which have 1 cutting edge.  Clipper blades have 2 cutting edges which move past each other and must be in close contact to work properly.

– However DIY sharpening on a flat stone rounds down the tips of your clipper blade so the face becomes convex and when you put these convex surfaces together the teeth of the clipper blade are splayed apart and do not cut.

How do you sharpen clipper blades?

The cutting teeth of your clipper blades need to be in close contact to work well.

To achieve this we sharpen each clipper blade with a slight hollow so that the tips of each blade slightly point into each other. This gives very good contact between the cutting teeth so the blades will work well.

DIY sharpening on a flat stone rounds down the tips of your clipper blades making the face convex. When these convex blades are put together the cutting teeth are splayed apart and will not work.

Why not sharpen them Flat?
You might think a flat surface would be best, however DIY flat sharpening produces convex and not flat surfaces and professionally flat sharpened clipper blades can perform inconsistently. Practically a small hollow is most reliable.

Why Hollow?
If you put 2 concave (hollow) surfaces together the edges are touching and there is a gap in the middle. As the teeth are at the edges of your clipper blades then a small hollow does work well.
Conversely if you put 2 convex surfaces together the middle is touching and the gap is at the edge. If you sharpen your clipper blade like this then the teeth are splayed apart and your clipper blade will not work.

My new or sharpened clipper blades don’t work?

Sometimes you can buy new clipper blades or have them professionally sharpened and they don’t cut.

– This comes from inaccurate sharpening rather than bluntness.
– Inaccurate sharpening has 2 types; blade surfaces that are convex and blade surfaces that are too concave.
Professionally sharpened blades have hollow or concave inside faces which gives the teeth good contact. However if the hollow is too deep (side to side) then there is a gap in the middle between the 2 blades, so the cutting teeth do not meet and wont work well.
DIY sharpening on a flat stone usually produces a convex surface that will not work as the teeth are splayed apart.

Can I sharpen my own scissors?

No (Not Usually!)

– Sharpening scissors blades is not like sharpening knives which have 1 sharp edge.  Scissors have 2 edges which slide past each other and these need to be in close contact to cut well.

– Scissors need both sharp cutting edges and correctly maintained inside faces to work well.

– Using a knife sharpener removes metal from the inside face of scissor blades which means the cutting edges can no longer meet and the scissors wont cut. If too much metal is removed by a knife sharpener then it wont ever be possible to sharpen your scissors again.

What are A5 clipper blades ?

History
The original A5 Clipper & A5 Blade were patented by John Oster in the USA in 1960 (US2928171A) and are similar to an earlier 1939 John Oster design (US2182597A). By the mid 1980’s Oster, Andis and Moser all had popular clipper models that took A5 type blades and made A5 clipper blades to go with them. Nowadays A5 blades have become the standard type of detachable clipper blade and most clipper brands sell a range of A5 blades as well as clipper models to go with them. An updated version of Oster’s original 1960’s A5 clipper can still be bought today and most of its components are interchangeable with the original 1960’s model.

Design
A5 blades are a type of clipper blade which “snap off” your clipper in one piece without unscrewing them so you can easily remove blades and swap them to any A5 compatible clipper.
A5 blades have a bracket on the back which has 2 small “wings” at the sides of a central a backplate.
A5 compatible clippers have a spike on a hinged bracket which the A5 blade slots onto and rotates back onto the clipper head. On A5 animal grooming clippers the A5 blade locks into place with a small latch mechanism.

Cutting Lengths
– Dog grooming A5 clipper blades have a range of cutting lengths numbered: #50 cuts 0.1mm, #40 cuts 0.25mm, #30 cuts 0.5mm, #15 cuts 1mm, #10 cuts 1.5mm, #7 cuts 3mm, #5 cuts 6mm, #4 cuts #12mm, #3 cuts 16mm and 3/4″ cuts 19mm.
– Barbers hair clipper blades are numbered differently: #00000 (0.1mm), #0000 (0.25mm), #000 (0.5mm), #0A (1.2mm), #1 (2.4mm), #1A (3.2mm), #1 1/2 (4mm), #2 (6.3mm), #3 1/2 (9.5mm), #3 3/4 (13mm)

Cutting Width
– Standard A5 blades the cutting teeth are around 45mm wide
– Narrow “Toe” A5 blades are around 15mm wide
– Wide A5 blades are wider than normal and around 65mm wide.

Ceramic A5 Blades
If your A5 blades get too hot while clipping fitting a ceramic cutter part can help reduce this. We can fit a new ceramic cutter as part of clipper blade sharpening for £2 extra see: Ceramic Clipper Blade Sharpening.
Ceramic cutters only fit normal width A5 blades and not narrow toe blades or wide blades.

The picture below shows the back of a A5 Toe Clipper Blade and you can see the 2 wings on the sides of the central bracket which sits in the middle of the wider tension spring.

What are Ceramic clipper blades ?

Ceramic blades work the same as normal clipper blades but the smaller part called the cutter, is made from ceramic instead of metal.

Why are some clipper blades ceramic ?
– Ceramic usually stays sharp longer than metal.
– Ceramic does not heat up as much as metal so the blade runs cooler.

What are the disadvantages of ceramic clipper blades ?
– Ceramic clipper blades are harder to re sharpen so sharpening usually costs more.
– Metal initially performs better, but ceramic stays sharp for longer.
– Ceramic is brittle and easily damaged.

Which blades can be ceramic ?
– Normal width A5 clipper blades.
– Some small trimmer blades like Liveryman Element and Classic.
– Some Wahl hair clipper blades.
– Andis Outliner and Slimline Pro.
– Occasionally Heiniger style horse clipper blades have a ceramic part.

Ceramic parts are challenging for a general sharpener to sharpen to a high standard so we fit a new ceramic part instead.
