Perhaps the only way I can describe Pennsylvania’s knife laws is disappointing. Upon cursory review, you might want to congratulate the state for being so pro-knife: you can own virtually any kind of knife except automatics and switchblades, and may legally carry pretty much any other kind of knife you want, to include such common legal targets as daggers, dirks, bowies, machetes and others.
But there is a dark side to Pennsylvania’s law and it is not immediately apparent after a casual read through. Pennsylvania knife laws frankly make prosecuting on the grounds of a violation or assumed violation of the knife law entirely too common and too easy.
This is another state that relies heavily on legal precedent and a working knowledge of the state’s history when it comes to knives. Learning both is essential for knowing exactly where you fall when carrying a knife concealed or openly in the state.
To complicate matters Pennsylvania lacks statewide preemption on knives, and one of its cities, Philadelphia (among others) is home to the absolute most restrictive knife laws in the entire country. This is a state where you will be quite literally on edge the entire time you’re carrying a knife outside your home. We will try and unravel this complex puzzle below.
What You Need to Know
- What Kind of Knives Can I Own?: Any kind of knife except switchblades/automatics. Assisted-opening knives potentially included. Exceptions exist.
- Can I Carry a Knife Concealed Without a Permit?: Yes,Any kind of knife except a switchblade.
- Can I Carry a Knife Concealed With a Permit?: Yes,Any kind of knife except a switchblade.
- Can I Carry a Knife Openly?: Yes,Any kind of knife except a switchblade.
The only category of knife that Pennsylvania explicitly bans from ownership are switchblades and any knife that is designed for the infliction of bodily injury with no “common lawful purpose”.
Specifically, the statutes also specify that one may own a switchblade so long as it is in a collector context, meaning at your home and specifically in place as part of a collection, not ready to be used as a weapon for defense.
Unfortunately, the nebulous language used to define switchblade in the state of Pennsylvania puts assisted opening knives on perilous ground. Many otherwise entirely common and pedestrian knives make use of spring-assisted operation to open, even though they are not opened by a locking button or lever release mechanism. You should possess and especially carry assisted-opening knives with the utmost caution.
Also understand that Pennsylvania explicitly bans any kind of knife that is designed for the infliction of bodily injury with no common, lawful purpose.
A common and lawful purpose is not defined in the state statutes, and this makes it extraordinarily likely there will be interpreted to mean whatever the police, the prosecution and the judge want it to mean.
Know that Pennsylvania’s total lack of preemption concerning knives has made several cities and other localities fertile ground for insanely restrictive knife laws.
Probably the crown jewel of knife lunacy in America is dubiously granted to Philadelphia, a place where you are completely forbidden from possessing any knife of any kind whatsoever outside of your home unless it is directly related to work or a task that you are currently engaged in.
Philadelphia defines a cutting weapon as any tool with an edge capable of inflicting a cutting wound.
Be careful out there…
Concealed Carry, No Permit
One may be in possession of any knife so long as it is not an offensive weapon. Pennsylvania defines an offensive weapon as a dagger, knife, razor or cutting instrument with a blade that is exposed in an automatic way via switch, push button, spring mechanism or otherwise.
Though this sounds very much like the language typically encountered in other states that ban these types of knives from various circumstances specifically, it is referring only to knives that open automatically, i.e. a switchblade.
Be warned that Pennsylvania has made it very easy for the state to prosecute people for weapons violations or presumed weapons violations, and you should carry any knife more threatening than the smallest, most pedestrian folding knife with extreme discretion.
Concealed Carry, With Permit
Pennsylvania makes no distinction when it comes to carrying a knife with a permit as opposed to without a permit. The only way you should ever carry a knife concealed in Pennsylvania is with great and deliberate care.
The open carry of any legal knife is permitted in Pennsylvania.
You cannot carry any knife of any kind into a school building or onto school property, be it public or private. You also cannot carry your knife into any courthouse or courtroom.
Pennsylvania has the potential to be a fine state when it comes to knife ownership and knife carry, but currently it only has one half of the equation down pat.
You may own nearly any kind of knife except a switchblade but when it comes to carrying a knife you’re only one mistake away from being charged with weapons possession thanks to some questionable statutes and a history of prosecuting against civilian carry and ownership of knives.
The whole thing is made worse by the state’s total lack of preemption law.
