Plastic blade!
The noise level is good they are quiet. It is a pain that they have to be cleaned out every 3-5 minutes and if you have a dog with fine yet thick hair/fur these are not the clippers to purchase. I’m honestly very disappointed. I purchased based on reviews  and everyone saying they are good when in fact they are not.  Far from a “PRO” clipper set.  They are easy to use and the oil light is helpful but again they cut u even with the plastic blade. They have to be cleaned out to often for being for dog grooming, a dog doesn’t want to sit there and wait for you to clean clippers out every 3-5 minutes. Again disappointed.
