There is a gentleman on Facebook, who modifies Swiss Army Knives (IMODSAK on FB ).
He takes your standard everyday SAK, and customizes them. Adding copper, wood, or titanium scales. Pretty much anything you want.
He also acid washes all the tools.
Here are some of his pics:
I ordered one from him, with solid copper scales.
Here is mine when I received it:
Crappy pic, but that's all I have right now.
Once I received it, I contacted a master engraver in Thailand, and sent the knife to him.
Here are some examples of his work:
He does very nice work, and has a long waiting list.
He recently started on mine.
Here are some pics:
That's just one side, he still has a ton of work to do, but it's going to be the coolest thing I own once it's complete.
I already have plans to send some other copper items to him for some engraving work.
Will post more pics as I receive them.
