The teeth are not metal or plastic but an engineered polyamide and polyacetal resins, used in car manufacturing and other applications replacing plastic and metal, making them flexible but virtually unbreakable with normal use. The teeth are tapered to the tips and won’t scratch the pet’s skin like other combs as they flex up and down and left to right while gliding over the pets joints. This material also will not damage the hair shaft as metal does.
*Cat’s and dogs that normally don’t like to be groomed will enjoy the feel of these combs. The teeth are curved like a claw but not sharp, they get down and under the mats and so are able to remove enormous amounts of undercoat hair, much more so than ‘straight’ wire brushes and combs. Each comb measures 4″ x 3″ x 1/2″ thick. See videos of this comb in use on You Tube.
* They have a very comfortable handle which makes it easy to maneuver the comb into all different positions, even if arthritis is an issue for you. We find the E2 comb works well on most hair lengths and pets. The E1 would be best choice for very short, close to the body hair, and certainly the E3 best for very long hair. We’ll happily exchange it if you order the wrong one.
