I’ve always figured that straight flat edged points, i.e. not serrated, are more for artful appearance or simply left to be touched up when actually going to be hunt. My understanding is the name of the game is death by exsanguination.
Seems to me that “flat edged” points pierce more than cut. Would a dull piercing point do the job? Maybe...so may a field point for that matter? If a dead elk is my goal, I’d want the sharpest edges I can flake out. Heck, I take the time to razor sharpen steel broadheads before a hunt...my thought is a stone/glass point should not be put to less scrutiny...actually more!
That said, obsidian sure can get sharp. Lately, the more I work it the more I like it.
Cheers, guys.
