I'm not familiar with this product, but Handamerican gets great reviews by those who do and for keeping a blade in decent shape for a few or more months, I suspect it would work very well indeed. Eventually you would need to bring it to a stone. The question I have is, why pay so much? Chromium Oxide can be had for a better price at
Classic Shaving and just about any leather will do. A glass plate or even a counter top would work as a flat surface rather than the plate. You could even splurge and get yourself a 2 or 4 sided paddle strop from Tony Miller over at
The Well Shaved Gentleman and you'd be able to get more paste options.
As far as the stones go. If you wanted to learn how to hone your own razor, most of us use the Norton 4,000/8,000 grit waterstone and would be able to advise you quite well indeed on developing that skill. Some guys, yours truly included, like a little more zing than the 8k provides and will go to an ultra fine finishing product like the Chromium Oxide or a superfine stone.
What are you thinking for a blade? There are great deals to be had in the classifieds here.

PS I don't think the deburring thing would work well with a razor.
