Yes, and I for one, would also like to know the purpose. What is the can ha=
lves=20
going to be used for?

And here is my contribution...

Make a fixture of two parts with a holow half-can space in both. Put the ca=
n in=20
one of the fixture part and close it with the other fixture part but use so=
me=20
spacers to just let a circular saw blade go through it at the top and botto=
m.

Use a high rpm circular saw to saw a slit through the top and bottom. It ma=
y be=20
possible that the saw can saw a slit lengthways (top to bottom) in the can =
also=20
(using another fixture with spacers at top and bottom instead of lengthways=
).=20
If not, use another tool, some sort of cutter where one blade is thin enoug=
 to=20
go throug the slits in the top and bottom and then cut the can lengthways.=
=20
Could possibly be done by hand with a pair of scissors.

The fixture halfes could be made with several spaces for cans on a row wher=
e=20
the top and bottom of several cans could be slitted at once.
