Abstract

In this paper we have constructed a new class of thin-shell wormholes from black holes in Ho\v{r}ava-Lifshitz gravity. Particular emphasis is placed on those aspects that allow a comparison of Ho\v{r}ava-Lifshitz to Einstein gravity. The former enjoys a number of advantages for small values of the throat radius.
