The versatile Dual Inoculation Tool can be used as either a palm OR thumb tool, quickly delivering a measured amount of sawdust spawn into each hole. This spring loaded brass and wood inoculator is a reliable tool will last for years if cleaned regularly during the inoculation season.

We use this to plug our shiitake logs and also inoculate our sapling raised garden beds...an all round great tool for the mushroom enthusiast who likes to cultivate outdoors.
