Spring Assisted Opening Knives

Spring assisted opening knives, or assisted knives as they are sometimes known, are legal in most areas in the US, UK, Canada, & Australia. Spring assisted knives are an excellent alternative to automatic knives and switchblades and are not subject to the same regulations. US federal law made it official that spring assisted knives be made in the US because they understood that these knives are very convenient to carry around and are fun and easy to use.  You just give the blade a push via the thumb-stud (and many of the knives have flippers that you can press as well) and the knife takes over opening the blade the rest of the way!  Most can be opened with one hand, using only one finger to open them.
