I must say that, for the time being, I am not very impressed. I haven't been able to find a great deal of information on King and Queen picks, and therefore haven't been able to get much information on the lifting technique they implement. However, so far, they are not as good as my bogota rakes, nor my Sparrows worm rake.
Don't get me wrong, they work, sometimes...
I've tried them on some cheapo "Wren Bird" night latch locks I had. These have decent bitting, and are based on Yale keyways, Y1 / 999, however they have really sloppy tolerances. My picks work fairly well on these locks.
I also tried them out on some custom pinned locks, different brands, different bittings, and have only had some modest success. I find I have more success with Bogotas or worms...
Any one out there had more success with these picks?
I also saw that Sparrows now has the rook and knight rakes, which resemble the king and queen but with slightly more agressive bitting. Anyone try these?
