How does assisted opening knife work




















Higher-end models tend to prioritize edge retention and toughness. These blades will perform better but will be harder to sharpen. You can learn more about common steels used in knife blades on the BladeHQ website. The longer the blade, the bigger the knife on your belt.

Assisted opening knives typically use a flipper mechanism or a thumb stud for one-handed opening. A lot of models give the option of both. For this reason, most knives that use this mechanism have an additional safety lock.

Some knives are designed for use with either hand, but others favor right or left-handed users, either in the design of the grip or the positioning of the thumb stud or locking system. There are plenty of assisted opening knives to choose from and your choice is likely to come down primarily to budget and personal preference — how the knife feels in your hand.

They open by the ambidextrous thumb stud on the blade with a slight bit of pressure. They are commonly confused with switchblades, but have one main difference. Site Information. Well what does that mean? There are differences between a Switchblade and Assisted Opening Knives. The opening mechanism functions the same way; the knife engages when a button releases the tension of the spring onto the blade.

An assisted opening knife, sometimes called a spring-assisted knife, is a knife that springs open only after the blade is slightly pushed open with force. Unlike the switchblade, nothing holds down the assisted opening knife when it's in the closed position. As the user begins opening up the blade with a thumb stud or flipper lever, which has some resistance, the spring or torsion bar catches the knife and propels it open where it locks into place. For a more detailed look at how the torsion bar works in an assisted opening knife, check out this great video that dissects a Kershaw assisted opener.

A good indicator of whether a knife is considered a switchblade or an assisted opening knife is what the resting position of the blade is. If the blade's natural inclination is to open without the presence of a hindrance, it's a switchblade. If there is nothing blocking the blade and it stays closed, the knife is an assisted opener assuming it has a mechanism to help open the knife.
