Dual Row Dimple Lock Picking Tool
This was purchased from Shenzen Hua Hong Locksmithing Co.
The tools are decsribed as YuanZi lock pick tool on the sellers site. I don't know whether YuanZi is the name of the lock these pick or the name of the manufacturer. In any event the lock appears to have a crescent shaped keyway with two rows of pins. The three tools appear to correspond to the three pin configurations available for this lock. Notice that one of the tools/locks has three (3) pins on one side and two (2) on the other -- this is most unusual. I don't yet have a lock for these tools but I have a rough idea what I am looking for.
In terms of design concept these tools are in a similar category to the Sputnik except they are purely picks and have no decoding ability.
