Being a life long machinist/mechanic the first time I encountered a primer crimp, I immediately thought of a countersink. I had a few in my tool box (60 degree x 1/2" on a 1/4" hex shaft) and deburred/decrimped 100 45 ACP cases. Now and with several thousand cases decrimped, I have had zero problems. While not a "dedicated reloading tool", it is effecient, inexpensive, easy to use and easily found in any good hardware store. I have intentionally over cut some primer pickets, even down to about 3/32" chamfer (0.093") and have had no primer blow outs/blown primers.
