Your request for "high end unusual intricate handle" makes me think of Bloodroot. They can turn almost anything into a handle and I absolutely love mine... Downside is the wait list is currently 4+ years.
Ian and Mike are among the top for a full set with flawless great handles but there are a lot of options, Maumasi, Cimms, Randy, Mert, Bill, etc... (lots of great makers) and Devin of course.... a lot of makers are pushing the envelope, new materials, inlays, etc. lot to choose from... :angel2:
I would also say Michael rader, his handles are the most involved I have seen and his knives cut with the best of my blades. I agree with inzite also tho halcyon forge can make you a very nice blade as well as probably being 50% the cost of some of the others listed above (even less in some cases)
If it's all about the intricate handle then I'd vote for Houston Edge Works, Nora Knives, Michael Rader, Jelle Hazenberg (more for his shapes and faceted contours), and maybe HHH Knives (Randy Haas).
