Ribs In larger needles there is a ribbed section to
provide a secure grip.
Square Body Needles can also have a square body for increased
strength.

Cutting Needles
Conventional Cutting NeedleThis needle has a triangular cross section with the apex
of the triangle on the inside of the needle curvature.
The effective cutting edges are restricted to the front
body which continues for half the length of the needle.
Reverse Cutting NeedleThe body of this needle is triangular in cross section,
having the apex cutting edge on the outside of the
needle and particularly increases its resistance to
bending.
