Multitools have changed over the decades, constantly improving functionality and design. What doesn't change however is the sheaths and holsters we use to hold our beloved tools. We have the traditional leather and the old standby of ballistic nylon but no major multitool company offers anything other than those two options. There are some tools that have the option to add a pocket clip but not everyone likes the weight of a Surge hanging from their pocket. People looking for alternative sources for sheaths will likely see the plethora of folks offering kydex sheaths. Kydex is extremely popular with law enforcement and military because of durability the material offers as well as the attachment options like the molle system.
