44 Lines about 88 Wrenches
Honestly, I'm not 100% sure. I've never been to one before.

Apparently lockpicking is a popular event at these events around the country, but they've never had anyone offer to set up a picking booth at the local one they hold each year. The organizer of this one wanted to learn how to pick, so she did a little searching online and sent emails to several of us in the area who are active on the forums and I agreed to teach some lockpicking classes over the weekend.
Spent some time this week gathering and ordering supplies but didn't feel like spending a buck or two apiece for tension wrenches, so this morning I cranked a few out.
Used flat stainless steel wire from windshield wiper inserts. Didn't have anything that would shear it cleanly, so I used pliers and bent it back and forth a few times to break them off at the lengths I needed. That left a rough edge so I used the wet grinder to smooth off the ends, then deburr the edges.
Here is a closeup of the ends, after grinding. For scale, each of these is about 3/32" or 2mm wide.
Grabbed a pair of channel lock pliers, made a long bend to use in the bottom of the keyway, and a short bend to use in the top of the keyway, and finished!
Not exactly artwork, but it'll get the job done.
Total time from start to finish, about two and a half hours for 88 wrenches, or about a minute and 45 seconds per wrench.
Hopefully the next batch will go quicker now that I have a routine for it.
