This is worthy of a quiz.
1) The inventor is an engineer and his day job is aeronautical inspector and therefore how likely that he went thru production and left the back door open i.e. "undoing the other side"?
2) Why is it different from other locked skewers?
3) Why did he focus on the front wheel?
4) Why did he think that there is market for this product?
