with my running and overall skills I'd probably stab myself in the eye

"There are countless horror stories": no doubt there are, if you try to seel defense products. If you wear a weapon-ish thingy you will not feel safer, but me more anxious, expecting something to happen. And it is very doubtful that a person not training in fighting will have any better cards when wielding such a device, which would require profound techniques to be really effective.. Besides that, I do not have statistics for that, but I am pretty sure that the chance of tripping are several order of magnitudes higher than that of being assaulted...and when tripping this device by design my be harmful in that you could cut yourself. A suggestion: team up in the autumn and winter...particularly when you need to run with a headlight, and in fog, it is a much better feeling to be at least two, and probably bring a dog if you or a friend have one that likes to run. Even more if you run long and get quite remote. And this is not only true for women, but also for men.

Looks good but not practical...would hurt you more during a punch because the Ring is putting torque on your finger...a well placed Punch/ kick would be more effective.

self defense classes would be better if you got the time and money. It's not guaranteed the lady will know what to do if the situation comes

There is already a similar weapon called Kakute. It is a ring with spikes and they are used for scratching or twisted into the attacker and is very painful. You can find some on ebay.

It is literally a lethal weapon.... This is a close to knife on your finger and you can easily pierce open a jugular with it. But brass knuckles are illegal in most states. What? In fact, this product is better for assault than it would be for self-defense...

So say u did get assulted, u used the pink plastic knife, u would properly get arrested for carrying/ using a deadly weapon! And then get sued by the attacker! Our laws protect the criminals.

In Britain it would get you a criminal record for carrying a dangerous weapon...!!

What's going to stop an attacker also buying this?

What a wonderful world .....

damn... looks like a weapon Rambo would use

No one punches like that - you're bound to break some knuckles. I think pepper spray is a much better alternative.

Recon you would probably damage your fingers really bad when using one of these, rather stick with a decent pepper spray in your hand. Can be used for punching and spraying.

This is illegal in the UK...possession of pointed and bladed weapon

Should be banned!
