I have been anodizing titanium since 2009 and have learned a lot after anodizing thousands of pieces. If you have anything made of titanium you would like to get anodized, please feel free to contact me using the contact page and I can quote you a price. For a general idea on what I would charge, for something up to the size of a large folding knife, I would charge $15 plus shipping back to you. If you need the piece polished, stone washed, or sandblasted as well, it would be $30 plus shipping. Any knife handles that need to be anodized must be removed prior to shipping. I cannot anodize pieces with anything attached to them, such as screws or knife blades.
Here are some examples of pieces I have anodized for customers:
