This interactive map summarizes knife carry laws by U.S. state, including common length thresholds, prohibited types, and whether open or concealed carry is generally allowed. We list sources and a last-verified date so you can review the primary materials. Laws can change quickly and may vary by city, county, or special location such as schools and courthouses, so always verify the current rules before carrying. Use the Blade Legality Checker to sanity-check a specific combination of length, type, and carry mode. For sharpening and buying decisions, explore steels in the Steel Explorer, plan your Grit Progression, or browse essential accessories.
