First stop was a trip to Hobby Lobby with a picture of the concept knife on my cellphone. I couldn't find the exact paint match I was looking for but figured these would work. Also picked up some Frog masking tape and various paint brushes, Hobby Lobby has it all pretty much. Arriving back at home, I realized my "Tahiti Blue" needed to be more green. Luckily I had some yellow car touch-up paint and kept adding a little yellow several times until I got to my desired color. I thought the accents in the picture looked orange, but now I'm thinking they're more red and might redo those parts.
Next I disassembled the knife but not completely. I left 2 of the 6 handle screws in to keep the action intact, not brave enough to actually go with a complete disassembly . . . yet. Taped up some parts holders and got to painting. First I put down a base of Platinum to cover the black thinking it would work better with my blueish frame paint. I also painted the screws Platinum and let everything dry overnight before adding the orange.
Over Saturday and Sunday, I put down at least 3 thin coats of paint, making sure there was ample drying time between coats. I also swapped out the 2 unpainted handle screws with painted ones late Sunday evening. Monday morning before heading to work I put everything back together, having let everything dry overnight. And here's the finished project, a good $660 cheaper than the concept, including original knife and supplies costs. I'm pleased with it and happy to have the savings set aside for other knives.
I think I was using a Disney copyrighted word that was preventing my first upload. 
I have heard that from my dad before! 
Can't help you with the silver knife, don't know who makes them either,
