Grooming Cats and Dogs

Question
I am the Marketing Manager for ANVIL USA.  We are the largest private label manufacturer of grooming scissors in the USA.  I am contacting as many dog groomers as possible on new product introductions; pertaining to the needs of the groomer.  The choices are many as to tools.  Which scissor works best for you?  What scissor works best for different breeds?
Would a double serrated blade edge be benefitial to you as a dog groomer?  All answers will be considered.  Please give me your opinion.
I thank you for participating.

Answer
Hello Barbara, My favorite type of scissor:  I always use an eight and one half length and light weight for scissoring poodles and such.  I use a thicker width blade for cockers and breeds where the hair would bend the light weight blades.  I love the light weight scissors however find the tips go out quick.  Thanks for asking.  Cindy lou :)
