A handle for supporting and effecting motion of an effector fitted to said handle along an axis, said handle comprising:

• (a) a fitting portion for fitting said effector and defining said axis;
• (b) a shank connected to said fitting portion directed distally to said effector at an approximately 45.degree. angle from said axis;
• and
• (c) a thumb loop connected to said shank further distal to said effector and defining a pear-shaped inner cross section having an arcuate end of a first inner radius proximal to said axis, an arcuate opposite end of a second inner radius distal said axis, said second inner radius larger than said first inner radius, and having two substantially straight sides each tangentially connecting said arcuate ends on opposite sides, said cross-section having an axis disposed to said shank at an angle from approximately 19.degree. to approximately 26.degree. further from said axis and with a first inner radius proximal said shank of approximately 0.175 inches to approximately 0.250 inches and a second inner radius distal said shank of approximately 0.400 inches to approximately 0.4250 inches, said first and second inner radii separated at their centers by a distance of between approximately 0.925 inches and approximately 0.945 inches.
