Keyring nub

[Etna]

When the keyring is removed from a medium-sized Victorinox, the nub it was attached to sticks out like a sore thumb.

I know lots of people here file away the nub entirely, but I wonder: can the nub be filed down just enough to produce a pointed tip that can be used as an emergency glassbreaker?

No, the steel would be too soft to work reliably, and so would be just an annoyance without adding to the utility of the knife.
