Have any of you seen this and what do you think of its effectiveness?

It is a serrated durable plastic finger ring knife.
I think coupled with a razor sharp Spyderco knife, perhaps a serrated Hawkbill or other type, would be a very good duo.
Do you think the same laws that govern bans against ceramic and plastic "letter openers" on air planes would effect this if the person wanted to travel by plane with it?
