I was told by the guys at my local kyak shop that you can heat it up to get the handle out if you use five minute araldite.

Maybe try a hair dryer..It should not hurt the carbon fiber..imo..Let us know if it works.

cut off the section that the handle is attacted to before you heat it up
if you are reducing the length
then have a go without damaging the rest of the shaft
good luck

Greenmoon,
If you cut the paddle at the lenght you want by carefully cutting around a little bit at a time and try and twist the handle off, if you are carefull enough, the handle will come out without scoring and then all you have to do is clean up the cut area. The key is to only score around the paddle a little bit at a time. I assume you are only shortening it by a little bit so the area you need to cut will have the handle shaft in it. Do a tradesman job and it will come out like brand new.

Used it this morning and super stoked I managed to get the handle out. It was definately too long.
Feels alot better but still could be abit shorter?
Im definately not gonna glue it in... yet
