Hi there:
You can make all the inside and outside gouge hones
and slips you want at very little cost and they will
fit each of your tools better than the store bought
offerings.
For gouges, you have any number of choice's, from
hardware-store dowels and pre-cut wooden shims, used
for leveling furniture, to art-store paper tortillons
and blending stumps. Slips can also be easily cut
from scrap wood.
If you know a wood-turner, have him/her turn some cone
shaped pieces, from basswood (whitewood) sugar pine or
mahogany, etc. in the appropriate sizes. Take your
gouge and run it along the length on one side,
removing enough material for a regular (outside)
profile.
Apply honing compound and there you go, a custom
fitted tool for your tool. Do one for each gouge and
label the larger end-grain end.
Look at this link to see the general shape you want to
end up with, keeping in mind that the Woodcraft tool
is intended to be a muti-tool platform. You can
easily tailor one of these for each of your gouges!

By the way, you can also use automotive wet/dry and
industrial 'sandpapers' to sharpen the inside (as well
as outside) profile by simply cutting manageable
pieces and holding them to a correctly sized dowel or
wood slip.
If you take a small staple gun and tack the paper down
to the dowel or slip, you can make a number of these
in different grits. Of course you will always need to
keep the staples away from the gouge edge. You can
also use glue, I recommend the 3M spray on type.
Automotive papers and 3M industrial papers will do as
good a job as any wet stone out there, including the
8000 grit Japanese stone!
ALWAYS PULL YOU TOOL THROUGH, NEVER PUSH, AS YOUR TOOL
WILL CUT INTO THE HONE/SLIP OR PAPER!
Cheers,
Eli
