Thanks! These are indeed similar to what I remembered. They are not quite identical, but certainly the same idea. I think the ones I saw, came with the bottom half of the key to turn the lock and the brush had to slide in over this.
I always wondered if picks like this work? It seems that the bristles would tend to lift all the pins with the same force, so lift them all to the same height, if it wasn't for each pin binding as it reaches the shear line? - Like impressioning.
I must admit to being disappointed at them only being for Schlage and Kwikset though. I would have liked to have been able to justify buying them so I could play with a set, but I can't really. However, I'm hoping for advanced access one day, if only to find out how those cruciform picks work
