Frequently Asked Questions
Is this practical for actual use?
For light cutting tasks, yes. This is a backup tool, not a heavy-duty knife. Good for opening packages, cutting cordage, or emergency situations.
Can I take this through airport security?
No. Knives of any kind are prohibited in carry-on luggage. This is for everyday carry, not air travel.
How does the folding mechanism work?
The card unfolds through several hinges to create a handle and expose the blade. Takes a few seconds—not fast like automatics, but discrete.
