Strange hadrons as dense matter probes

The spectra of strange hadrons have been measured in detail as a function of centrality for a variety of collision systems and energies at RHIC. Recent results are presented and compared to those measured at the SPS. The effects of the system size on strange particle production and kinematics are examined. I place specific emphasis on comparing A-A to pp production and discuss how strangeness can be used to probe the dense matter produced in heavy-ion collisions.
