C.R.S. Const. Art. No. 2, 13: “The right of no person to keep and bear arms in defense of his home, person and property, or in aid of the civil power when thereto legally summoned, shall be called in question; but nothing herein contained shall be construed to justify the practice of carrying concealed weapons.”
Knives that are Illegal in Colorado
Gravity knives, switchblades, and ballistic knives were illegal to possess in the knife laws of Colorado 2016 and the code was C.R.S. 18-12-102.
Universal Citation: CO Rev Stat § 18-12-102 (2016)
“(1) As used in this section, the term “dangerous weapon” means a firearm silencer, machine gun, short shotgun, short rifle, or ballistic knife.
(2) As used in this section, the term “illegal weapon” means a blackjack, gas gun, metallic knuckles, gravity knife, or switchblade knife.
(3) A person who knowingly possesses a dangerous weapon commits a class 5 felony. Each subsequent violation of this subsection (3) by the same person shall be a class 4 felony.
(4) A person who knowingly possesses an illegal weapon commits a class 1 misdemeanor.”
Here ballistic knives are included in the “dangerous weapons” and gravity knives or switchblades are included in the “illegal weapons”.
Possessing this dangerous weapon or ballistic knives knowingly is a class 5 felony. And possessing these illegal weapons such as gravity knives and switchblades knowingly is a class 1 misdemeanor.
From the newly updated law of August 9th, 2017, with the code C.R.S. 18-12-101, gravity knives or automatic knives are no more illegal or dangerous to possess in Colorado.
But still, “Ballistic knives” are illegal and mentioned as the dangerous weapon in the section. So, the ballistic knives are totally banned in Colorado now.
“(a.3) Ballistic knife” means any knife that has a blade which is forcefully projected from the handle by means of a spring-loaded device or explosive charge.”
What will happen if you still possess one?
If you possess this dangerous or deadly weapon, “ballistic knife”, it will be a felony offense and you will be punished by,
- a year (1 year) or more years in jail and/or,
- a fine of $1,000-$100,000.
Concealing knives & Length of the Blade is Important in Colorado
If you are there for fishing and hunting then all fishing and hunting knives are legal in Colorado with no fixed length of blade size.
It will be a class 2 misdemeanor if you conceal a knife knowingly or unlawfully.
Code 18-12-105 says,
“(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”
“3.5 inches” is the number you should remember always.
If the size of the blades of knives is over 3.5 inches, those knives are illegal. You cannot carry a knife including a dagger, dirk, stiletto or other dangerous knives concealed over 3.5 inches blade-sized. It will be illegal.
C.R.S. 18-12-101 says,
“ ‘Knife’ means any dagger, dirk, knife, or stiletto with a blade over three and one-half inches in length, or any other dangerous instrument capable of inflicting cutting, stabbing, or tearing wounds, but does not include a hunting or fishing knife carried for sports use. The issue that a knife is hunting or fishing knife must be raised as an affirmative defense.”
Knives less than 3.5 inches are not considered as dangerous ones and you can carry them openly or conceal easily.
Exceptions: In this statement, all fishing and hunting knives more than 3.5 inches blade size can be carried concealed. These are not illegal.
A Bowie knife, machete or sword, and hunting knives can be carried openly with any size of blades.
