That is really looking nice! You have a great eye.
Ah yes, the extra epoxy where the handle and blade meet. The best way to deal with this is to keep it from happening. Like lonehunter said, wipe it off before it cures. Once I get the handle all clamped up and the epoxy is done oozing out I wipe it down well in that area.
However, if you end up with epoxy there (and there always seems to be some on there no matter how careful you are) you can usually get it off. The first thing I try is to use a toothpick. Not those cheap flat ones that break, but the nice strong round ones. I can usually scrape off the extra epoxy with one of those and the toothpick won't scratch the knife blade. If there is too much epoxy for the toothpick, you can CAREFULLY use the tip of a small, sharp pocket knife to scrape/cut the extra epoxy. The other thing I have successfully used for this my buffer. You just need to make sure that the buffer doesn't scratch the blade either. My advantage is that I polish my own blades. That way I simply use the same buff and rouge for removing the epoxy as I used on my last blade polishing step.
Be careful using chemicals to remove the epoxy. If you find a chemical that removes the epoxy from the blade, it can remove the epoxy from between the wood and the knife tang if you get too much on there.
Just finished this one. It's another kit knife for a friend.
