The Sentinel Stripping knives are handmade and manufactured in Belgium under supervision of the famous breeder and groomer Rony Demunter. The materials used are a high-quality metal alloy which is stronger and lighter than other knives and very light - each knife weighs under 30 grams. The Beech wood used to produce the handles comes from sustainable European forests and the varnish is FCS approved as a safe A+ for the environment. 

The Sentinel stripping knives are available in five different styles of blade with either fine or wide handles to suit all groomers and each knife can be ordered in left or right-handed versions. These hand-crafted knives will not damage or break the coat and there is a knife suitable for all kinds of hand stripping, whether it’s detailing and finishing a show dog or for use on a commercial dog in the salon. 
The Sentinel Stripping knives have a lifetime warranty
