the Mrs wants to try her hand at clipping a few of these calves this year. We have one of the old HEAVY Oster Stewart shear master sheep shears. Went to TSC to see about getting cattle blades (see other post on TSC employees brain power) and all they could offer was a goat tooth comb. Came home and did some surfing,,,like the Andis. But which one? AG? AG2? AGC? Too confusing! Can someone tell me what to buy, for a beginner, and what blades. Only doing about 5 calves this year.
