Query: Most awesome dog grooming tool ever!!

My 1 year old Bichon Frise gets a lot of knots and mattings in his hair everyday from playing, and this tool gets rid of all of them!! It is very sharp, so you need to be careful not only for your dog's safety, but for your own. I try to use it every other day on him, and it really keeps away all the knots and tangles with regular use. So thankful to my dog groomer who recommended this tool to me as a good way to keep the tangles away in between professional grooming visits.
