Not so much the single bivel as broadhead design and strength. Fix two blade none aluminum ferral will always be stronger.

They have thicker blades and more steel and typically moderate cutting diameter.

Try an ulmer edge.


To anwser the question most north american game aren't that tough, and don't require two blade heads

The single bevels have sold me, especially with high FOC heavy arrow. I shoot a 58# recurve with 225 grain Tuffhead broad head and 225 grain stainless steel insert glued in Goldtip arrows. I shot a bear last year and the arrow broke the front leg bone on the far side with complete pass through. Penetration of that arrow is unreal. It's not real fast but it's fast enough. According to Ashby studies, the insert is actually the weakest point in the arrow.
