REMEMBER TO GREASE THE CUTTER NOTCH
A customer sent me her Bravura and several blades and complained the clipper was burning up and vibrating during her last groom. On inspection of these items I discovered there was nothing wrong with the clipper, but the blades had been melting while on the clipper.
The cutter notches on both blades sent were melted and rounded out terribly. I called and told her the clipper was fine (she was relieved), but I also fould out she cleaned the blades in soap and water. Washing them this way is fine, but most soaps will totally clean the blades of any oil and grease.
In the clipper head of your Wahl trimmer there is a round white cam with a silver post sticking out from it. This post sticks in the cutter notch, and as it spins it moves the cutter back and forth on the blade to make it cut. This silver post doesn't spin, its not on a bearing, it just pushes on the inside of that cutter notch and can create alot of friction if its not lubricated. This is what happened to these blades, the friction was so great from not greasing the cutter notch after washing that the revolving post melted the insides of both cutter notches. Below is a picture of both cutter notches, look closely at the inside of the notches and you'll see how they are melted out.
A 5-N-1 BLADE SPECIAL FOR VETERINARIANS
I received a different looking 5-N-1 blade recently. It had super fine teeth and had only one setting. The customer complained the blade never cut when brand new, and I could see by the tooth spacing it wouldn't go through the coat on many breeds. I called my factory rep and he said they did manufacture these blades for vets and they were for surgery.
I have a couple pictures of this blade below. You can see its not the blade you want to use in regular pet grooming. The first picture compares this vet blade to the fine blade that is commonly used. The second picture shows it has no adjustment lever, it has one setting.
I didn't do anything to this blade but test it. It went through my fine test hair but I had to go super slow, and it took the hair down past NOTHING LEFT! This is actually what a vet wants prior to surgery and this blade will do it no problem. If you happen to acquire one of these blades somehow, good luck, its not going to be what your used to using.
Not a long post this time but I wanted to share what can happen if you forget to grease the cutter notch. It can cause friction and hurt the cutter notch, or make you clipper run hot and vibrate. This information is also for sharpeners as well as groomers. Sharpeners can run across these problems from their customers, and now they have answers.
We have a lubrication guide for the 5-N-1 blade on our website, and we return a copy to customers who send us 5-N-1 blades for refurbishing. We refurbish these blades with new parts for $10 each, see the website for more details.
