My own Hanko
Hanko is the "generic" name for seals used in Japan - they are still pretty common in many places where Western people would use a signature.

ShoDo works are traditionally signed by the author using one or more seals (but note that those used by calligraphers have a more specific name: 落款 rakkan) and often adding a handwritten signature.

At the moment I own a few plastic or wooden rakkan from Japan and a couple stone ones from China - if you want your own seal I wholeheartedly endorse JUN Japanese Gifts & Souvenirs

I have also experimented with having a modern inkstamp made to my specification, as a temporary replacement for a more traditional rakkan. If you want to do the same, here is what I did.
