I did this for a long time until I recently found out that this can actually cause you far more damage than your attacker.
It’s much more efficient and you’re less likely to harm yourself if you instead keep your hand in a fist with your keys sticking out the bottom by your pinkies so you can make much more efficient stabbing motions.
OR curl your hand up into a fist and have a key that is grasped firmly and jutting out from under your thumb.
It gives you more control and is much less likely to hurt your fingers than the above methods.
