I make a lot of non folder knife handles, but I cannot carry them in WA state.
What do you mean you cant carry them?
In WA law, one can carry a fixed blade knife if not concealed...but the law is vague and the appearance of the sheath cannot be threatening.
But any WA local municipality can make any knife law. A fishing knife in a sheath on your belt violates many different laws as one drives down the freeway to go fishing.
Under the Seattle Municipal Code, it is illegal to carry any fixed-blade knife, including a dagger, sword, bayonet, bolo knife, hatchet, axe or straight razor, with a blade longer than 3 1/2 inches.Jul 2, 2014But there are 281 cities in WA state and the worst are the suburbs of Seattle that can be 90% liberal.
There are no local gun laws that superseded WA concealed carry. So I can carry a handgun but not a fishing fillet knife.
I have folder knives that are 3.5" blade for WA, and other knives for hunting out of state.
