When it comes down to it there is nothing better than manual tools for your Lock pick Set, whether they be retail, homebrew, macgyver style. DIY'ers look here.
nice case man.where did you get the leather?because ive been looking to make a case for a while(nothing like yours,just a small case for 20/30 picks) and i dont know whre to get the leather for it.thanks.
If you're looking for a small bit of actual dead cow, try a craft shop or paper store that carries bookbinding supplies. They'll have the tools to work with it as well.
