The following is a direct excerpt from the WI. statutes for concealed carry.

BEGIN QUOTE:

Wisconsin - 941.23 Carrying concealed weapon.
Any person except a peace officer who goes armed with a
concealed and dangerous weapon is guilty of a Class A
misdemeanor.

Wisconsin Case Law:

To "go armed" does not require going anywhere. The elements
for a violation of s. 941.23 are: 1) a dangerous weapon is on the
defendant's person or within reach; 2) the defendant is aware of
the weapon's presence; and 3) the weapon is hidden.
State v. Keith, 175 Wis. 2d 75, 498 N.W.2d 865 (Ct. App. 1993).

Judges are not peace officers authorized to carry concealed weapons.
69 Atty. Gen. 66.

So here in Wisconsin I can legally carry my Dog Father LE on my hip as long as it is in a sheath which lets the public see that it is a visible knife.
Which is quite evident! <img src="/ubbthreads/images/graemlins/cool.gif" alt="" /> <img src="/ubbthreads/images/graemlins/grin.gif" alt="" /> <img src="/ubbthreads/images/graemlins/thumbup.gif" alt="" />

NOBODY but LEO's can carry concealed here. But knives of any length are fine as long as they are displayed. <img src="/ubbthreads/images/graemlins/ooo.gif" alt="" /> <img src="/ubbthreads/images/graemlins/wink.gif" alt="" /> <img src="/ubbthreads/images/graemlins/thumbup.gif" alt="" />

Rainwalker lets me display mine in fine style wherever I go in Wisconsin and it's legal. <img src="/ubbthreads/images/graemlins/cool.gif" alt="" />
Got to love that law.

I wear two on my belt and carry 2 in my pockets and wear a necker whenever I leave the house. <img src="/ubbthreads/images/graemlins/blush.gif" alt="" />

Peace.
