Ancol Knot Buster

The rounded edge really does keep this gentle on my spaniel's skin while the blade slices through the worst mats behind her ears. I was honestly expecting to have to cut them out with scissors, so this saved her a lot of stress.

It does cut through mats on my spaniel's feathering, but I found the blade snags if I don't hold the coat taut first. Works fine for small tangles, less so on the really dense ones behind his ears.
