It is important to keep clipper blades lubricated, and not just "cooled" during use.  Clipper coolant usually contains alcohol, which actually removes the lubrication on the blade.  Additionally, they will accumulate byproducts from the organic materials they are cutting.  This makes them less efficient, and creates heat, dulling them sooner, and creating more work for the people using them.
If you are using clippers for a living, you already work hard enough.  So make your life easier, lubricate them during use, and clean as often as possible, at least every day before you leave work.
    There is a conflict of belief regarding the life and sharpness of ceramic cutters on clipper blades.  In general, the ceramic cutter will wear longer, when used under correct applications.  But, they are more fragile, so the teeth break easier than steel cutters.   If they break, they are more expensive than steel to replace.  They will chip if they encounter grains of sand, so make sure to shampoo thoroughly, and avoid using them to strip dogs if possible.  Since they are not steel, and can not be held magnetically, they are more difficult to work with or sharpen.  Some groomers love them, and others specifically request that we change them to steel after they have become too worn to sharpen.  Many sharpeners refuse to sharpen them.  We do, for one dollar more, to cover the cost of inevitable breakage during handling.
