This is a welcome change, given that many gun owners carry both firearms and knives for self defense. And many citizens carry ordinary pocket knives for utility purposes and have been unknowingly violating law.

However, many cities regulate knives at the local level making the state law moot. So a matching set of bills, House Bill 243, introduced on March 31 by Representative Al Cutrona, and Senate Bill 156, introduced on April 13 by Senator Kristina Roegner, seek to establish statewide "preemption." This would forbid all political subdivisions, including cities, from regulating the transportation, possession, carrying, sale, transfer, purchase, gift, devise, licensing, registration, or use of a knife or knife-making components.

Makes sense with the recent knife/weapon/automatics bill.

Agreed but even putting that issue aside it seems that every city, town, and burg has their own rules about all kinds of stuff like blade length, serrations, etc. this would be a welcome and overdue fix to the complex patchwork of regulations that currently exist.
