I was practicing tossing a knife from hand to hand.

While simultaneously changing the blade orientation from “north” to “south”.

While running up stairs.

At work.

I “caught” it!

By the blade.

With the webbing between the second and middle fingers oF my right hand, WHICH IMMEDIATELY SLIT APART.

A falling knife has no handle.

Also, throwing a knife from hand to hand just creates falling knives.
