I agree. I thought I lost mine on the trail. Searched the workshop about 5 times hoping I'd just misplaced it. No good! Wrote it off. Was going through spares the other day and found it in a ziplock bag with my rear indicator/blinker wiring harness! between then I had ordered an MSR 2T spanner low profile, would be great if it fit between the plug and the water jacket attachment
The GG plug spanner handle is also the allen key for the front axle incase anyone didn't know, and the handle on the screwdriver fits perfectly back through the plug end for leverage.
