RE: Arrow cutting
Because when you have ten people waiting for your time they tend to get irritated when otherpeople "nit-pick" things like this.
And the fact that far too many self proclaimed experts couldn't hit the barn walls if they were standing inside no matter what you did to their arrows.
And most people purchase the least expensive shaft to begin with and it isn't just the ends that's screwed up so it doesn't help many people all that much. I'd say that 80% of my sales are low grade shafts/ arrows. The vast majority of the bow hunters aren't as picky about their equipment as most of us here. See the thread titled "confusing".
A better question would be..... Why don't the manufacturers do this if it is a known problem?
