US Military Knives Confiscated?

[Bill Harsey]

Just call a phone call from lawmaker in New Hampshire who asked me if I have heard anything about United States military personnel returning from overseas having knives with blade lengths over a certain size (4 inches?) confiscated by US Customs.

Looking for actual instances of this from person from whom knife was taken.

Have another heavyweight lawmaker in DC ready to jump on this if we can find an example.

Any help is appreciated. Thanks.

Edited to add: By Military Knife I mean any knife owned by a member of the United States military and in their possession upon re-entry to the United States.

Yes this was prompted by stories of this happening. Trying to find some truth here.
