This thumb-press log inoculation tool is for injecting sawdust spawn into holes drilled on logs. It features a sturdy ergonomic hand grip and a spring-loaded thumb press for single hand use, allowing the other hand to steady the log during inoculation. With regular cleaning and proper storage, it should last for many years. 

Note: If you are planning to use plug spawn, you do not need a log inoculation tool.
