these heads used to be sold under a different name, i shot a buck with them and one year cause i didnt get my new steelheads in the mail before opening day and it worked great but of the six i bought 2 had 1 blade open stiffly and i just put them in box for messing with the other thing is get a sharpener for them theyll cut but they are not razor sharp. if your on a budget and want field tip accuracy these are decent heads honestly and my brother shot a deer last year with the onesi had left over from the previous year no problems. like i said sharpen them up and make sure they open freely.
