Instead of the edge angling up to meet the spine, a reverse tanto’s tip angles down to meet the edge. Like the American tanto, the reverse tanto offers a strong tip for piercing and, generally, a straight edge, ideal for good slicing.
A sheepsfoot blade is similar to the Wharncliffe, but it has a steeper slope from spine to edge and a less-pointy tip. They are often favored by emergency responders due to the relative safety of the rounded tip. The straight edge works well for slicing push cuts and general-purpose cutting.
