I'm the one with the other hook and yes, the name is close to yours or rather, the same but without the hyphen but really, what would I call it?
Also, I had no idea about your hook until someone else pointed it out to me. Luckily, the designs have nothing in common.
I was also toying with the idea to put a helmet on a helmet hook logo but since I see that you now added it to yours, I'll obviously refrain.
Good luck with the sales.
