Spear Point - Blade Geometry
Spear Point Info
A spear point blade is one that is symmetrical from top to bottom, and is essentially shaped like a dagger. The main difference between a spear point and a dagger is a spear point will only be single edged, while a dagger is double-edged. The edge in this context refers to the secondary bevel.
The diagram shows just one possible way the blade could be ground. Many spearpoints are ground the same on the bottom edge as they are on the top. The important factor is that the actual shape of the blade is symmetrical, not the grind.
