[I know this is super old, but in case anybody else has this problem and ends up here...]I had the same issue. I guess I must have torqued it too much one day, because the next day it was stuck tight. I tried everything (wetting, banging, heating, WD40, strap wrenches, etc.). I could not get it to budge even with me grabbing one end and a friend twisting the other. I was about ready to throw it out and buy a new one.But then I got the idea to stick a screwdriver through one of the holes on the "tool end" to give me decent leverage, and I drilled a similar (1/4") hole through the "handle end" so I could stick a screwdriver through there too. Then I wedged one end (with screwdriver) between a couple sturdy rocks to keep it from turning, and manually twisted the other end, using the screwdriver for leverage. You could use any sturdy rod instead of the screwdrivers, and if you can't find a place to wedge one end, just get a friend to help out.I was never happier to get my pool pole to extend, and now I'm much more careful about how much I tighten it!
