Questions & Answers

11 Customer Questions

I need to know the length of coat that each blade4 is used for. What blade would be good for say 3/4 of an inch? I have a Portuguese Water Dog that groomers either shave all his coat off or make him look like a poodle.
Answer by ChewyJul 12, 2018
The size 10 leaves hair 1/16 inch, size 15 leaves hair 3/64 inch, size 30 leaves hair 1/50 inch, size 40 leaves hair 1/100 inch, and size 50 leaves hair 1/125 inch.

I tried to change the blade. The assembly fell apart. How does it fit back together?
Answer by ChewyFeb 05, 2018
The blade should slide on easily and snap back into place.

can these blades be sharpened ?
Answer by ChewyOct 24, 2019
Blades should be soaked in a solution to break down oil and grime, and then a detail grinder is used to reshape and sharpen the teeth.

what blade size will leave my dogs fur about 1/2 inch long?
Answer by ChewyAug 29, 2020
Within the Oster Cryogen-X blades, the size 4F will leave the coat 3/8 inch, the closest to the desired 1/2 inch.

Not pleased

I have ordered these Oster blade 10 many times. This time the blade cut as a used blade. Not a clean cut at all. Very disappointed. All the time and effect for a crappy cut.

Worked great

I oiled the blade and sprayed some coolant on before I began. Blade cut perfectly. Had to be careful as my old blade had gotten so dull.

Oster 5 blade replacement

I groomed my show dogs back in the 70's, 80's, and early 90's then went dogless until August of 2020. Dug out my grooming equipment and saw my 10 blade was chipped. I was surprised to find I was able to order a direct replacement for equipment as old as it is. Love how cool this blade seems to run. What a great cut it is providing for grooming my English Cocker.
