Detailed Description
Sable IV
The Sable has one of the most practical and versatile of all the blade shapes. The full thickness of material on the back edge makes it a strong knife and the high grind and belly the blade offer a perfect utility knife which can double for most skinning tasks.
Each knife is made from a solid billet of A2 tool steel. This method results in two distinct advantages-the strength/weight ratio is exceptional and there is no handle/blade join. This means that there is no area where the blade and handle could come apart. A2 Tool Steel offers excellent edge retention and good shock resistance Hardness at between 55 and 57 Rockwell C is not brittle but gives good edge retention along with ease of sharpening.
