Washington state allows pocket knives for everyday carry, with no blade length limits statewide. Concealed carry faces restrictions for blades over 3.5 inches or certain types, and local ordinances add layers of complexity.
Allowed Types
Ordinary folding and pocket knives are legal to own, sell, and carry openly statewide. Spring blade (switchblade) knives saw deregulation via SB 5860 in 2024—now permitted generally, except in sensitive areas like schools.
Fixed blades like Bowie or utility knives qualify for open carry. No age minimum beyond 21 for some sales, but minors avoid prohibited spots.
Prohibited Knives
Gravity knives, balisong (butterfly), and metal knuckle knives remain banned for possession, sale, or manufacture. Concealed dirks, daggers, or dangerous weapons violate RCW 9.41.250 as gross misdemeanors.
Intimidating display anywhere triggers RCW 9.41.270. Schools, jails, and liquor areas ban knives universally.
Carry Regulations
No full preemption—cities enforce stricter rules.
Penalties and Updates
Gross misdemeanors carry up to 364 days jail and $5,000 fines. A 2025 bill (SB 5534) aimed to further ease spring blade rules but stalled.
Verify local laws in Seattle or Tacoma for compliance. Washington evolves toward leniency for common tools while safeguarding public spaces.
