Mis-Punched Scope Probe Hook

Back in the day, HP scope probes had a rugged music-wire hook on the tip:

These days, scope probe tips use ordinary sheet steel punched into a hook shape:

Siglent scope probe - good tip
Siglent scope probe – good tip

By sheer bad luck, the first probe out of the bag had a mis-punched end with no griptivity:

Siglent scope probe - mis-cut tip

Dunno what happened, but it was definitely sheared off in the factory.

After I finally recognized the problem, I shaped a crude hook with a safe-edge needle file and continued the mission:

Siglent scope probe - filed tip

A quick note to Siglent put a replacement probe tip in the mail, so it’s all good.
