This is a medium size binder clip tab. I use all sizes for different locks.

With pliers squeeze on the round bend on each side to achieve the following shape:

Side by side comparison:

Make sure you end up with a very streamiled shaft and that both tangs are bent together perfectly parallel then heat up the clip with a soldering torch (soldering Iron takes too long). Once fully heated apply solder and it should flow on its own perfectly in between the groove. Do this on both sides.

File down the solder after cool to make a sleek profile. Ends can be trimmed to desired widths to adjust for different bittings. These are by no means high tech or ground breaking but they work well and are very durable. Longer clips can be used to make picks with 2 wards on them for locks that require such. I have made hundreds of these and usually put them on keyrings for easy portability.
Love 'em, hate 'em?
