Claim 7:
8. Ergonomic snips comprising:
(A) first and second elongate gripping levers, said gripping levers having leading ends and having trailing ends forming respective first and second hand gripping portions;
(B) first pivoting means for pivotally connecting said first and second gripping levers at said leading ends;
(C) first and second elongate blade levers each having a distal end formed as a cutting blade and a proximate actuating end;
(D) second pivoting means for pivotally connecting said first and second blade levers to each other at a point intermediate said distal cutting blade and proximate actuating ends, a line extending through said first and second pivoting means defining an axis of the snips;
(E) third pivoting means for pivotally connecting said proximate end of said first blade lever to said first gripping lever;
(F) fourth pivoting means for pivotally connecting said proximate end of said second blade lever to said second gripping lever;
(G) a first handgrip covering said first hand gripping portion of said first gripping lever and including a first anti-slip ear generally extending in a direction away from said axis and forming a proximate surface for engaging a user's thumb axially spaced from said first pivoting means a distance “f”; and
(H) a second handgrip covering said second hand gripping portion of said second gripping lever and including a proximate second anti-slip ear generally extending in a direction away from said axis axially spaced a distance “b” from said first pivoting means, and also formed with an outwardly projecting protrusion at a leading end of said second handgrip covering spaced a distance “a”, said second anti-slip ear and said protrusion being spaced from each other along said second handgrip covering to form an elongate finger-receiving portion, a transverse dimension between said finger receiving portion along a direction substantially normal to said axis to said proximate surface of said first anti-slip ear when said first and second hand gripping portions are in a closed configuration is “d”, and b≈2d, a≈d and said finger receiving portion is equal to (b−a), and wherein (b−a) is within the range of 39-45 mm.
