Corona Pro Cut Shears Locking Tab

The locking tab on my Corona Pro Cut shears broke and it will not lock closed.  Designed this as close as I can to the original, but beefed up the weak spots.  I'm including a second .stl with an extended tab so I can pinch it to open instead of just using my thumb.  Left-handed folks may appreciate this feature.

This locking tab may also work with Corona Dual Cut shears.
