Call up Kavalinka. They have some teardrop blades that they use often in their track forks. They have access to Tange and Kaisai tubing which isn't common here in the US. They do custom machining too, so they can make you a real nice fork blade bender in whatever style curve you want. Or dropouts too. Trace out the design. Pricing is actually quite affordable. You might get slammed on the overseas shipping charges though.
