How do you make a lockpick?

Answer 1

It depends on the lock. There really isn't enough information here to answer the question.

For some locks, all you need is a paper clip or two. For others, you'll need very precise tools that are made from different materials. Sometimes spring steel works best. Other times high carbon steel works best. Sometimes the pick has to be able to flex and sometimes it needs to be strong and rigid.

For most common locks, hacksaw blades can be used to make picks and essentially all one has to do is grind the hacksaw blade down to the shape of the desired pick.

Unfortunately, this answer can't be more specific than that because the target lock isn't known.
