I usually clean out the wood
chips on our Oregon
battery powered chainsaw with a nearby twig, but a small paintbrush
gets the job done faster and cleaner.
Two bungee cord straps on the
chainsaw handlebar keeps the brush handy.
If the brush had a flat head
screwdriver as part of the handle it would make tightening the chain in
the field easier.
Sounds like a new project to me. I don't see why you couldn't bore a hole in the handle of the brush and epoxy a small screwdriver in it. Probably not putting allot of torque on the screwdriver so it would probably outlast the brush itself. Might even patent it and sell it back to Oregon if they were interested.
