It is a contact weapon, and even the most inexperienced user can manage to plant it where it will do some damage. As one DEA representative once said of the knife, "They never jam, and they never ever lack ammo." These advantages of the early car knives apply similarly today for both guys and women.
In the United States, there are several layers of policies that car knife customers require to be familiar with. Each state manages 'switchblades' or auto knives differently, and there are several federal statutes that manage the sale, manufacture, import and interstate transport of these products. Auto knife customers need to be familiar with the patchwork of nationwide laws when travelling with their preferred blade.
ON the other hand, 21 states have some sort of limitation on vehicle knives, which can vary from a near-total restriction to merely requiring a weapon license to carry. They need cautious review as there are a wide range of exemptions and limitations for each jurisdiction. 10 states or territories completely prohibit automated knives and are a no-go for legal carry.


Lots of states define length limitations, varying from 1. 5 inches to 3 inches maximum. Others focus on double-edged blades or call out 'stiletto' or 'dagger'- type blades that have no cutting edge however are intended for straight thrusting. For a protective knife, like a Benchmade OTF Infidel, a longer blade is generally better than a much shorter one.
For slashing attacks, the longer blade can cut much deeper to reach tendons and cut muscle, which will eliminate an attacker's movement. The majority of protective knives fall under the 2. 5- to 4. 0-inch variety, which strike a balance between practicality and effectiveness. Knives with folding or withdrawing blades are limited in size by the length of the blade, with undeployed blade length representing one-half of the deployed blade length of the knife.
5-inch blade knife will have about 3-inches of handle to keep, so the longer blade length offers you more to grip. The Most Complete Run-Down translates into the amount of leverage or force you can direct into the target and how well you can maintain control of the knife. There are a couple of kinds of automated knife style offered: out-the-front or OTF knives, single action, OTF double action and side-opening.
