A knife over 3.5 inches is considered a concealed weapon. Even a Colorado Concealed Firearms Permit does not allow you to carry what is defined as a knife there, it just covers firearms. Basically if you use it for work or are going, and or coming from and activity that requires it you should be OK, but I never carry anything over 3.5 inches just to be safe, unless I was hunting, fishing, hiking, etc, and I do have a CCW permit, which again does not matter.
Question for you, sir. This is an except from Colorado statute:
18-12-105. Unlawfully carrying a concealed weapon - unlawful possession of weapons.
(1) A person commits a class 2 misdemeanor if such person knowingly and unlawfully:
(a) Carries a knife concealed on or about his or her person; or
(b) Carries a firearm concealed on or about his or her person; or
(c) Without legal authority, carries, brings, or has in such person's possession a firearm or any explosive, incendiary, or other dangerous device on the property of or within any building in which the chambers, galleries, or offices of the general assembly, or either house thereof, are located, or in which a legislative hearing or meeting is being or is to be conducted, or in which the official office of any member, officer, or employee of the general assembly is located.
(d) (Deleted 1993.)
(
2) It shall not be an offense if the defendant was:
(a) A person in his or her own dwelling or place of business or on property owned or under his or her control at the time of the act of carrying; or
(b) A person in a private automobile or other private means of conveyance who carries a weapon for lawful protection of such person's or another's person or property while traveling; or
(c) A person who, at the time of carrying a concealed weapon, held a valid written permit to carry a concealed weapon issued pursuant to section 18-12-105.1, as it existed prior to its repeal, or, if the weapon involved was a handgun, held a valid permit to carry a concealed handgun or a temporary emergency permit issued pursuant to part 2 of this article; except that it shall be an offense under this section if the person was carrying a concealed handgun in violation of the provisions of section 18-12-214; or
(d) A peace officer, as described in section 16-2.5-101, C.R.S., when carrying a weapon in conformance with the policy of the employing agency as provided in section 16-2.5-101 (2), C.R.S.; or
(e) (Deleted 2003.)
(f) A United States probation officer or a United States pretrial services officer while on duty and serving in the state of Colorado under the authority of rules and regulations promulgated by the judicial conference of the United States.
It appears as though you are okay with a 4" Spyderco Military IF you already have a concealed weapons permit to carry a concealed handgun. Please explain, as I am thinking of gifting such a knife to my CCW-carrying son in Colorado.
Thanks for your reply,
Sonny
