It's a crap shoot. I had on inspector think long and hard over my old fingernail clipper with a hinged file.
Most new clippers no longer have that feature.
A few years ago I was in Dakar Senegal for work. Going through security for the flight back my toiletry kit, which is always in my carry-on, was flagged on the scanner due to a similar nail clipper. The security agent said I could keep it if he snapped the nail file off...was not worth the time or energy to discuss it with the guy...one nail file-less clipper and I was happily on my way.
