The original Wharncliffe knife had a strong, thick blade with a rounded spine that gradually tapered towards its straight cutting edge, forming an acute tip. The current day definition of a Wharncliffe blade has become slightly broader and includes a variety of blades with slightly curved spines. Unfortunately, this sometimes leads to lambsfoot blades being mislabeled as Wharncliffe blades. Wharncliffe blades can be single bevel / 'chisel ground' or double bevel and are available with fixed blades or folding blades. Recently, Wharncliffe folding knives have become increasingly popular amongst a small, but dedicated section of the online knife community.
