Yes, with practice a 2cm wide hone can be used. Of course it will take more time and runs a much greater risk of damaging the blade with a single mis-stroke than is not flat to the hone but it can be done. If you choose to go that route, especially with Ebay razors that require a lot of work, you will save yourself a lot of frustration by investing in a wider bevel setting 1k hone. That is the workhorse of the set.
