They were originally supposed to mimic common kwikset key biting and used as profile picks like raimundo said. I believe they were computer generated picks by Romstar, but correct me if I'm wrong.
I personally never really got the hang of using the standard king and queen. I have never made more, so I'm afraid I can't be a tremendous help. I do use columbian royals fairly often, but the method for those is practically identical to a bogota.
I think your best bet is to start jamming them into any lock they will fit into and hammer on 'em till you get results

Seriously though practice with them and you'll probably get the hang of it. I used the king with a gentle rocking motion, and the queen in much the same way except with the halfdiamond tip it's easier to rock the pick up to set high front pins then spp the rest with the tip.
