Key to fixing a flat tire

[eco4arcs]

I wish I was joking but I'll be gathering first hand experience fixing a flat on my hawk now that I have the obvious culprit removed from my knob by.

I've had flats from screws, nails etc... but never a key. It almost makes me think somebody was fu<kin with me... a flat key wedged at that angle is suspicious...or maybe I am paranoid.

One question for the group, do you all think the tire is safe to continue using at "hawk speed" riding?

Thanks
