Depends on size, training, and other matters. A minor slashing weapon like a key and with an intent to go for an eye can be useful in some contexts.
Key projecting from the fist, bunch inside the fist, can be a serious impromptu puncture weapon to soft tissue areas of the body
I'm so ugly people run the other way when they see me. 😉 But, if I was better looking I'd carry a side arm after learning how to use it safely. I was an IPSC Range Officer in the late nineties and highly recommend it for anyone wanting to carry. https://www.ipsc.org/
