The possibility of buying or transporting switch blades or automatic knives remains severely restricted or prohibited in much of Europe, with a few notable exceptions. In the UK, the foldable switch blade type is commonly referred to as a slide knife. In the UK, knives with an automated opening system are almost impossible to acquire or transport legally. Although they can be legally possessed, it is illegal to manufacture, sell, rent, give, lend or import such knives. This definition would theoretically limit legal ownership to “grandfathered” automatic knives that were already in the possession of their owner before the enactment of the law in force in 1959. Even if such a knife is legal, carrying it in public without a valid reason or legal authority is also illegal under applicable UK law. In 1837, Tennessee banned the concealed carrying of Bowie knives and Arkansas toothpicks. 22 Tennes-Gen. Assemb.
Acts 200, chap. 137 (1838). An 1838 bill to add pistols to the secret ban on carrying was defeated. Tennessee Legislature, Daily Republican Banner (Nashville), Jan. 13, 1838, 2. The Tennessee Supreme Court upheld the ban on concealed wearing in a famous 1840 case. Aymette v. State, 21 tenn. (2 hum.) 154 (1840).
Unknown craftsmen developed an automatic folding-tipped bayonet for use on flintlock guns and transport guns.   Examples of automatic steel folding knives from Sheffield in England have crown marks dating back to 1840.  Cutlers such as Tillotson, A. Davey, Beever, Hobson, Ibbotson and others produced self-opening knives.  Some have simple iron jaws and wooden handles, while others are adorned with embossed silver alloy jaws and deer handles.  Knives made in England often include a “pin release” instead of a center handle knob, through which the larger blade activated by the mainspring is released by pressing the smaller closed blade.  The company`s bid was approved by the U.S. Army Materiel Command in December 1940 as the Knife, Pocket, M2.  The M2 had a 3,125-inch Clip Point blade and had a transport depot. With the exception of the bail, the M2 was in every respect a copy of George Schrade`s popular civilian Presto security button model.
The M-2 was distributed primarily to U.S. Army paratroopers during the war, although some knives were apparently distributed to crews and members of the Office of Strategic Services. When the M2 was delivered to paratroopers, it was usually carried in the pocket of the double-zipper knife on the upper chest of the jacket of the M42 jumping uniform. After the war, the M2 was manufactured by Schrade (now Schrade-Walden, Inc.) as the Paratrooper`s Snap Blade Blade Knife (MIL-K-10043) as part of a postwar military contract. In addition, other companies such as the Colonial Knife Co. produced civilian versions of the M2 after the war. Although section 1 of the Act is prohibited, section 4 contains an exception allowing the open carrying of some of the above-mentioned weapons without handguns: “Provided that no person shall be convicted of violating the above-mentioned act which openly carries Bowie knives, dirks, toothpicks, spears and which are clearly visible… The same section also allowed sellers to sell inventory they already had until next year. The first spring-loaded switch blade that could be authenticated appeared in the late 1700s, probably built by a craftsman in Italy.  After 1816, automatic knives were not produced in Italy for 50 years due to the laws of the Austro-Hungarian Empire.  By 1900, Italy had resumed production of automatic needle knives, all handmade by individual cutlers or small cutlers.
Most of these cutlers were concentrated in the towns of Maniago, Frosolone, Campobasso and Scarperia. Yes. You can carry hunting and fishing knives for sports use. In fact, hunting knives and fishing knives are not included in Colorado`s legal definition of “knives.” In 1904, George Schrade, along with his brothers Louis and William, founded the Schrade Cutlery Co. in Walden and began developing a new series of switch blades, which he patented in 1906/07.  Schrade`s new safety push-button knives included several design improvements over his previous work and featured a handle-mounted control knob with a sliding safety switch.  A multi-blade control knob allowed the knife to operate with up to four automatic blades.  In successive patents from 1906 to 1916, Schrade constantly improved this design, which later became known as the Presto series.  With the Presto line, Schrade would largely dominate the market for automatic knives in the United States for the next forty years.
