I saw a how-to on the instructables website, and gave it a go
http://www.instructables.com/id/Pipe-Tools,-Garden-Shovel/
A bit of pipe, cut halfway through
then lengthways....
carefully bent out with pliers....
A bit of hammering.....
shaping with a hacksaw and file.....
finished, and a hollow handle for loopaper or a bag.
It took about 20mins to make, and a better finish could be done with more care.. This waas steel piping, about 1mm. I think aluminium wouldnt be robust enough...
