I am slow. Anyway.... here is more info on the Wahl Peanut Trimmer. It comes with the one blade of course, but also comes with 4 cutting guides (1/8" to 1/2"). Wahl "peanut" clipper/trimmer weighs less than 4 oz. and is less than 4" long. the power and performance of a full-size clipper with the versatility of a heavy-duty trimmer. comes with four snap-on combs from 1/8" to 1/2".
I could not find the blade size, except for a site that sold the replacement blades and lists them as a #30:

If you want to buy them locally, Sally's Beauty Supply has them for $59.95 but if you order online, some places have them for as little as $37 and there is now a cordless version for @ $52. I would like to have the cordless but I hate to change anything from this great little trimmer.
I think so highly of these little trimmers because they have the same power as a larger clipper. But for a beginning groomer, they can be used much easier and especially with small dogs, they can be easier to maneuver in tight spaces.
