Sawdust Spawn Thumb Press Log Inoculation Tool










Grip dimensions | 4”(L) 1.25”(W) |
Our spring-loaded thumb press log inoculation tools are perfect for injecting sawdust spawn into holes drilled on logs. Designed for single-hand use, these tools allow the other hand to steady the log during inoculation. With regular cleaning and proper storage, they should last for many years.
Choose from two grip styles:
- Ribbed Anti-Slip Handle: Designed to decrease friction that causes blistering
- Curved Ergonomic Handle: Designed to decrease movement for increased comfort
*Tool handle colors may vary
Caring for your inoculation tool:
Sawdust spawn residue can build up in your tool, making it feel sticky or causing the plunger to freeze. If this happens, soak in hot soapy water for 30 minutes, then push down on the head of the tool to loosen any debris.
Periodically check the head of the tool to make sure it is not coming unscrewed. The tool can be tightened by using a large flat head screwdriver. Insert the screwdriver into the groove on the tip, hold onto the head and lightly twist the screwdriver until tight.

Heavy duty well constructed tool
This thing is made to last! Plastic grip is comfortable and should prevent hand fatigue from long usage. The brass tube is sturdy enough to hold up to vigorous use.

Great Tool
Finally received my order, and used the inoculation tool. The only problem that I had, just a nuisance more than a problem, but the tool got stuck easily in many of the holes, but worked great.

Could not say itany better then Pete
"Y’all, this tool is amazing! Paired with the drill Bit that’s literally made to fit this puppy right into the notch, an unbeatable combo! This made my sawdust inoculation so much quicker. It’s super sturdy and very comfortable to hold."

Right tool for the job
Solidly built, perfect tool for log inoculation.

Made the process easy!!
During my first test run, I was very surprised at how easy this tool was to use, and how fast I was able to inoculate some logs. I have a ton of logs to do, and was afraid it would take me several days, in the cold. Thanks to the tool, I know I can breeze through it faster than expected. Now I need to get a 2nd one for my wife, so she can help, lol.
