This one is driving me crazy, I know I’ve seen this logo before and I’m pretty sure it is an artsy rendering of the letters in either the company name or the lock name - perhaps of the letters H, I, C and or D. I may be totally off base about this too, but I’m pretty sure I’m going to lie awake in bed tonight trying to figure it out. This really bugs me because I know that I not only saw a similar lock but there was a paragraph of text explaining the logo.
