Practical Details

Legal in most US states as a utility blade, but check local knife laws before carrying. Blade stays sharp through normal use but can be resharpened if needed. Comes with protective sleeve to prevent wallet damage. Stainless steel construction means it won’t rust from wallet moisture or humidity.

This isn’t about tactical situations or self-defense scenarios. It’s about having a cutting tool when you need one and don’t have access to anything else. The kind of everyday emergencies where any blade solves the problem immediately.

Common Questions

Will this damage my wallet or other cards?
The knife comes with a protective sleeve that prevents the blade from contacting other items in your wallet. The smooth edges won’t catch on fabric or leather.

How sharp is the blade?
Sharp enough to cut rope, tape, plastic packaging, and fabric. It’s not a precision cutting tool, but it will handle emergency situations where you need to cut through something quickly.

Is this legal to carry everywhere?
Knife laws vary significantly by state and locality. This qualifies as a utility blade in most jurisdictions, but some areas have restrictions on blade length or concealed carry. Check your local laws before carrying.

How durable is it for the price?
It’s a $5 emergency tool, not a lifetime investment. The stainless steel will hold up to occasional use and won’t break during normal deployment, but don’t expect heirloom quality at this price point.
