Seam Ripper
Seam rippers are generally allowed in carry-on because of their small, enclosed cutting hook, the same as a sewing kit.

Carry-on details
Generally allowed. A seam ripper's cutting edge is a tiny, partly enclosed hook rather than an open blade, so it's treated like other small sewing tools rather than a knife. TSA doesn't list it as prohibited, but as with any pointed item, the individual screening officer has final discretion at the checkpoint.
Checked-bag details
Allowed. No restriction in checked baggage.
Special instructions
If you want to avoid any chance of a second look, pack it in checked baggage instead — this is a low-risk item, but officer discretion always applies to pointed tools.
