I bought a great pet scissors, a Fromm 11 B groomer, 26 years ago, in St. Paul, Minnesota, for my then cairn. It has been great until the last couple of years with my now cairn. Where can I find a comprable shear? I bought scissors at Sally Beauty Supply, but it does not work that well. I just need a good one to trim feet, tail, face, ears, and the "sanitary". What should I get and where?
