A Century of Puzzlement
The beginning of the period of “puzzlement” is a decision by the California Court of Appeals in 1928, namely People v. Ruiz, 263 P. 836. It involved the application of the California restriction to the 1917 dirks and daggers statute.

The Virginia legislature passed a law in 1849 that made it unlawful to "habitually carry about hid from common observation any pistol, dirk, bowie knife or weapon of like kind." The use of the adverb "habitually" is consistent with the concealed carry anti-dueling measures of that era. A few minor changes have been made in the years since.

On June 23, 2022, the U.S. Supreme Court announced its decision in the case of New York State Rifle & Pistol Association, Inc v Bruen. The knife community welcomes the confirmation of what we understood to be a limitation on the government. While knives are rarely used as weapons, people have a right to defend themselves and carry items - "arms" - suitable for that purpose. This right includes knives.
Read More »Circumstances of Possession
When interpreting laws regarding the possession of knives, courts have occasionally opted to incorporate a “circumstances of possession” element into a statute, thereby rewriting the law.

The legislative history behind the Federal Switchblade Act of 1958 (FSA) reveals that enforcement issues and uncertainties were foreseen due to the “many exceptions” it provided. A “huge” problem was pointed out to legislators by the Secretary of Commerce when he read the bill before it was passed.

The question of which knife is legal in all 50 states was recently posed to the American Knife & Tool Institute (AKTI).

Philadelphia's ordinance was truly one of the worst in the country. While a ruling of law from a court would have more force and be harder to overturn than an agreement between the parties, this is a good result and another option in the Bruen toolkit.

The statutes in this category typically establish an exemption from general prohibitions regarding the carry or possession of specific knives.
Read More »Location – Location: Sensitive Spaces
Knife laws with location-based restrictions on the possession and carry of knives can be placed into three categories, namely home/residence, public carry, and sensitive location. These restrictions are premised on the view that the restricted knives are weapons. Culinary and table knives are rarely the subject of possessory limits despite the fact the same are often employed as weapons.

A complicating factor when deciding whether and how a certain knife may be carried is the existence of multiple layers of legal restriction or “law.” In the United States, we have various levels including federal, territorial, Indian Country, state, and “local.”

A severe restriction on the public carry of knives in the City of Seattle has been protected for decades by questionable rulings emanating from small majorities of the Washington Supreme Court. Those rulings are a tangled web which, when unraveled, is recognized by the high court of that state that aspects of Washington knife law violate the state and federal constitutions.

Read More »The Bowie Knife Frenzy
The American Knife & Tool Institute suggests that restrictions based on an identifier such as “bowie” fall far short of explicit standards. During the bowie knife frenzy, the legislation created was intended to address the destructive vestige of trial by combat. Those laws, some of which remain in effect, were well-intended but defective from the outset. The term “bowie knife” remains in common use and is casually applied to a broad range of knives without common characteristics apart from a sharp edge and blade that tapers to a point.

This piece is intended to address the basic questions concerning the routine public carry of pocketknives concealed in one’s pocket or handbag. Millions of us in the knife community carry a "pocketknife" type every day and have done so for a lifetime. If doing so created some threat to an orderly society, evidence of the same would have been obvious.

In this article, we examine whether the restrictions imposed on automatic knives by the Federal Switchblade Act (FSA) are constitutional, given the Second Amendment to the U.S. Constitution. Those restrictions are not insignificant of consequences. The FSA provides a penalty of up to five years imprisonment and or a fine of up to $2,000 for a violation.

This article is not a case review, but one that I think is both festive (we can still be festive, right?) and interesting. It is a story that ties into one of the most important legal issues of the day for knife owners–the dreaded Federal Switchblade Act, 15 USC 1241 et. It also shows how that Act is both incomprehensible AND anti-business.
Read More »The Long and Short of It
Knife carry restrictions based on blade length are common across the United States. Distinctions that derive from a measurement – as opposed to name or type classification such as poniard, dirk, or bowie – offer a higher level of objectivity or predictability. In some instances, a blade length limitation is combined with or serves as an alternative basis for legal restriction.
Read More »The Misunderstood Dirk
Very little guidance is provided in either statutory or decisional law as to what differentiates the dirk from any other knife. Most case law from across this country involving dirks, arises from attempts to indiscriminately, or elastically, apply a dirk restriction to some other non-restricted knife for the mere sake of a conviction.

It is prudent for those in the knife community to be aware of the aspects of knife law that often escape our attention. While many of us might know what styles or blade lengths may lawfully be carried in the state in which we live, the consequences of even a simple possession violation can be far more profound than what is perceived.
Read More »The Pocket Clip Conundrum
Whether “pocket clip carry” - a knife clipped to a side pocket along the trouser seam - is concealed or open carry is an ongoing controversy. The issue extends to knives clipped to a pocket on a purse or handbag. It is especially troublesome for people in the seventeen states where concealment is determinative as to what type or size of pocket knives may be carried with confidence that one is not violating a concealed carry restriction.

The ripple effects of Bruen continue as governmental units, federal and state, struggle to figure out just how to apply its test. A recent case out of California, Miller v. Bonta, 2023 US Dist. LEXIS 188421 (D. S. Cal. October 19, 2023) helps tease out exactly how the Bruen test works.

On April 4, 1956, the Governor of Pennsylvania signed two bills into law. The first of the two in the sequence created an entirely new section of the penal statutes captioned "Selling or Dispensing Knives, etc., Commonly Called "Switch-Blades." This new section made it a misdemeanor to sell, dispense, give, deliver, or offer for sale any automatic knife.
Read More »The Uncommon and Extraordinary Pocket Knife
If you are among the millions of people who routinely carry a pocket knife, you have probably been asked why you do so. Occasionally, the officious questioner will suggest that you violate some law because you have a concealed weapon. That individual typically declares that one does not need to carry a knife. A useful and polite response to such a question is to point out that Abraham Lincoln carried a pocket knife. He and his wife were viewing a dramatic performance at a local theater. Today, we might call it a “date night.” The contents of his pocket included eyeglasses, a handkerchief, a five-dollar bill, and a slip-joint knife with ivory scales and silver bolsters.

“Butterfly knife” seems to be the most common identifier for the folding knife that wins the award for the most flourishing opening performance. “Balisong” and “fan knife” are other identifiers.

Regardless of the outcome, one lesson above all comes out of this case: knife advocates should be mining these federal criminal cases for language and ideas to support knife owner rights. Because of the cost and risk of litigation, few places generate more good laws for the rights of everyday people than a public defender office.

The phrases “without any explainable lawful purpose” and “under circumstances not manifestly appropriate” which appear in New Jersey knife law sections are undeniably vague and indefinite...The ability to steer between lawful and unlawful conduct – choosing a “legal” knife - requires the laws must be precise.
