Pas tout.
Un couteau qui s'ouvre par thumbstud ça passe. Par contre un flipper entre dans la catégorie «centrifugal knife», qui interdit les trucs s'ouvrant par force centrifuge ou par un coup de poignet.
(b) Centrifugal knife (folding knife, butterfly knife, balisong knife) – A centrifugal knife is one that opens automatically through the use of centrifugal force. Centrifugal force may be defined as a force, arising from the body's inertia, which appears to act on a body moving in a circular path and is directed away from the centre around which the body is moving. That is, centrifugal force is established when the blade of the knife may be opened with the flick of the wrist.
