The 3 Major Handle Designs

Opposing grip is the oldest design, and the least ergonomically correct. The problem with this design is, it forces your thumb underneath your ring finger, thus creating a tremendous amount of stress and pressure on your nerves and tendons.

Eventually the shear manufactures realized that moving the thumb forward was a more ergonomically correct way to make a shear and the "offset" handle came out. Better... but still not the best from an ergonomic standpoint.

Finally the "full offset" or "crane grip" was developed. As you can see... it moves your thumb from under your ring finger to under your index finger. This releases all the pressure and stress put on the nerves and tendons in your hand and thumb. ALL of our SHARK-FIN shears are made with the Crane grip. Also notice that we don't use screw on finger rests as they tend to fall off. Ours are part of the shear... one less thing to worry about.
