"Most unusual, Captain ..." (Spock) I've had just the opposite experiance. I've found the RR to have very consistent pulls from knife to knife and blade to blade on the same knife. The one exception was a Baby Sunfish/Elephant Toenail. The main blade had a "5" pull, the secondary was between a "19" and "20". It was near impossible to open, even with pliers. I traded that RR off, and decided not to get another baby Sunfish -- ever. The three RR large Sunfish I have all have a "5" pull on both blades.
