Cutting Length

It is the industry standard when clipping to go with the grain of coat as it leaves it one clipper blade longer. If you choose to go against the grain of coat it will leave it much shorter, so for instance, a #7 clipper blade leaves the coat approximately 1/8" hair but when going against the grain of the coat, it will leave it 1/4".

How a Hair Clipper Blade Cuts?

There are two surfaces that make up the cutting edge, the front, and the back rail. These two rails are the points that are hollow ground to produce a new sharp edge. As the blade is used these edges start to wear and will eventually "round off", and it is at this point when your blade causes you snagging and dragging within the coat, your blade will need re-sharpening.


If you leave a build-up of hair in between the two rails, this can cause a further "rounding" off the cutting rails. So, it is essential that every 5 minutes, you stop clipping and brush off any excess hair from your clipper blade.


There is a spring that holds the top cutter and sole plate together. The function of the spring is to apply adequate tension to allow the clipper blade to cut smoothly. If that spring is too tight, the top cutter will not move from side to side easily. To test your clipper blades: with the clipper blade in your hand, try to move the top cutter from side to side. In the case of the top cutter not moving properly, the tension could be too tight and will need to be adjusted.

How to adjust the hair clipper blade tension?

To achieve correct hair clipper blade tensioning you will need a flat head screwdriver. Place the screwdriver into the side of the spring and gently lever-up to release the tension. Spray your clipper blade with oil, and check and test again. If the tension is too light, or too loose, this will result in a non-cutting blade.


How to tell when your hair clipper blade has expired?

Most hair clipper blades can be resharpened, but eventually they reach a point where they will not take a sharp edge and further sharpening is impossible. Any dull blades should be resharpened as a set; replacing only one blade or swopping a top cutter from one blade to another set will not work. If you are finding the clipper blade is snagging and tugging at the coat, it is time for it to be re-sharpened. A rule of thumb, if you clean and oil your clipper blades daily, then a blade will last between 10-12 weeks based on clipping 5 dogs per day.
