We prove that the class of topological knot types that are both Legendrian
simple and satisfy the uniform thickness property (UTP) is closed under
cabling. An immediate application is that all iterated cabling knot types that
begin with negative torus knots are Legendrian simple. We also examine, for
arbitrary numbers of iterations, iterated cablings that begin with positive
torus knots, and establish the Legendrian simplicity of large classes of these
knot types, many of which also satisfy the UTP.
We prove that an iterated torus knot type fails the uniform thickness
property (UTP) if and only if all of its iterations are positive cablings,
which is precisely when an iterated torus knot type supports the standard
contact structure. We also show that all iterated torus knots that fail the UTP
support cabling knot types that are transversally non-simple.
