I finally got my Delica plain edge. I like it a lot. It's so lightweight and it's fun to open and close one handed. I did it maybe a hundred times, so much that my thumb is red by dint of pressing on the tab of the lockback. I carried it easily without feeling it inside my waistband like Doug's picture, diagonally on the front like a samurai carrying his tanto. That will definitely be my urban EDC folder.
