Seems like the breaks in between the chain guards could get hung up on imperfections whereas a traditional rounded chain would kind of slide over them. Cool idea though.
Gona have to agree. Rock ledge, rail with chips and knicks or even wood would be too easy to get caught. Great for the coping on the edge of a quarter though.
Hahaha, I have dyslexia. Not very good at spelling, but that's just me. Anyway, this is a heavy duty-looking chain. Dyslexia is mostly for reading, just to throw that out there.
