RE: Serrated Expanible
the others are right...IF you were to cut your self with a razor and then cut yourself with a serrated edge...both just 1 slice forward...the serrated may make a nastier looking wound, but it will stop bleeding quicker and easier...DO NOT try it.....just think about being cut with a razor and getting cut with something that didnt make a nice straight cut...even paper cuts...them things bleed like crazy and pop right open when you think you finally got it closed! they are almost impossible to close if they are deep and long!
i believe serrations on broadheads are just to catch the hunters eye...they look cool and mean and nasty...sure they still cut and kill...but i'll take a razor sharp straight edge...
