Does anyone know about barbershop hair clippers/cutters. I have purchased a few cheaper models like the Harbor Freight kind and an Oster cheapo. They both do a terrible job and it takes several hours to cut my hair myself. I am thinking about getting an Oster Model 76 professional cutter, but I don't know what size blades to get. I always thought that clippers came with one set of blades, but there seems to be about a dozen different sizes. I do not mean the plastic stand-off combs that are used for height adjustments. I mean the actual metal cutting blades.
