It doesn't look like it would eork, but boy it Rocks! This is by far the greatest brush to get that pesky deep undercoat. It's far safer than the Furminator and other blades and brushes. I have scraped across my skin with no issues. It is perfect for my Labrador. He loves it and I love knowing I finally found "THE SOLUTION". It truly does keep 95% of the hair off my furniture, clothes, floors- everywhere! Thank you!
