The Hack Saw, also known as "Lil' Hacker," is a powerful knife weapon used by Vykkers. They were originally designed as surgical tools, but have been re-purposed as weapons. They are the only usable close combat weapons in Munch's Oddysee that can be bought from a vendo and are exclusive to the Vykkers only.
Hack Saws can only be found in Hack Saw vendos and are often around when Vykkers are nearby and are highly damaging weapons. Unarmed Vykkers can choose from either a Hack Saw or a SnUzi, in contrast to the Slig Bouncers and Poppers who are automatically armed with battons or machineguns respectively.
