Not many customizers can say, "I need a new part. I think I'll design one in CAD and have it made." Ryan (AKA Thrash) is one of the few who can.
The dagger, sword, and fantastic helmet were all created as part of Ryan's entry into the CCCVIII Realistic Castle Figure contest. Not only are the accessories custom made, but the cape and torso decals are as well. Brilliant work!
I don't know if Ryan plans on entering the customs business any time soon, but with skills like these, I would say he's off to a good start.
