I'm pretty sure it means a wrench in the gears such as the title states. Basically the last 2 comments were correct Yeah

couldn't the gears represent the "machine"? and the wrench, those who oppose it? yes, yes they are. or at least that's the way i interpret this image. it's now on my forearm. have mercy. monkey wrench? nah..besides, it's an open-ended wrench. Hail_Hiroshima

I think that the meaning of this patch is more along the lines of disturbing the status quo. Why submit to the hum- drum of continuity? Make a difference! beck_me!

What about the poor sap that has to rebuild that machine? I recently just quit my job. fuck 2:45 to 11:15 work nights! moco-loco

I dont think its only reffering to monkey wrenching, Just my first impression, I was thinking more along the lines of slowing the rate of work if not totally abolishing it.Stop the 40 hour work week mutha fuckers!! Fuck 9 to 5 work days!! Fuck conventional work all together!! xXxAntiChristxXx

It's beautiful. I am yet to go on my first monkey-wrenching but I'm looking forward to it Anarcho Petoris
