TODAY’S PATENT- FOLDING KNIFE
The Folding knife was invented by Norman D. Poisson on the 24th of November 1998, bearing patent number US5839194A.
The invention relates to a folding knife which includes a blade which can be pivoted about a bolt between two halves of a housing, and which can be locked. In the prior art, particles may get into the opening of the knife i.e. sand or dust which especially in combination with sweat, fat, fruit juice, blood etc. form a padding which is fairly adhesive and resistant to pressure.
It is no longer possible to move the blade to its end position and the locking element can only partially and thus unreliably lock. The object of the present invention is to provide a dustproof folding knife which is to be opened and closed ergonomically with one hand, with the blade to be locked safely and clearance free.
