Rick Welch just made them the "OFFICIAL BROADHEAD" at DAKOTABOWS. I know Dave Oligee, owner of the company & will vouch for him & the broadhead. The sharpening system with the ceramic rods, in my personal experience, does an EXCELLENT job at getting my 100 grain Landsharks crazy sharp.
I know there are a ton of good broadheads available, I'm telling you I think the Simmons broadhead is among the very best, in my opinion.
I've had no problem geting them sharp, they are very durable,have great flight characteristics & Dave offers excellent customer service. He's readily avaiable to help anyone who has questions about his product. Here's his contact info. Best of luck.- Dave Mullins.
