I have a question we have a pair of sheep shears and two sets of subbeam hair heads, a star lister, and a A2 small animal clipper. I was wondering what blades i should use for my shears and then could i use my a2's to clip the tail head, the topline, and the head or should i get a new set of clippers like a set of a5's or a set of Andis 2 speeds from sullivan supply with the blocking blade. O wait or should i get a set ANDIS 64800 AGR+ RECHARGEABLE or a ANDIS 63855 AGR+ RECHARGEABLE and buy a blocking blade for it
