This is the VIPER Titanium Money Clip, in a natural titanium finish, from Superior Titanium. I particularly like this model because of it's larger size and the cutouts which allow a little decorative knot work.
I used black 1.4mm braided nylon cord to tie cobra stitches, also known as a Solomon bar/Portuguese sinnet, around the end cutouts. I like my first attempt, but I think I may try a couple more knot work ideas on it and will add those to this blog post if I like how they come out. Maybe something like a wallet lanyard to clip to a belt loop...
The VIPER can hold up to 60 folded bills or 8 credit cards/ID with 30 folded bills and with it's strong spring grip can just as easily hold onto a single bill. It's also available in Black Diamond and Titanium Nitride finishes.
Superior Titanium also carries a variety of other titanium money clip designs as well as other titanium items including cuff links, tie clips, bracelets, chains, rings, tags, guitar picks, and business card cases
. As mentioned on their website, titanium is '45% Lighter Than Steel', 'Retains Shape 30% Better Than Steel', and is 'Corrosion Resistant'.
For the lanyard, I used the same black 1.4mm braided nylon cord in a cobra stitch/Solomon bar/Portuguese sennit, and a black clip/split ring from PhotonLight.com.
A somewhat associated item that I've made, are these money sign($) shaped paracord lanyard/fobs, one made with gutted paracord, the other with inner strands intact.
