Take a look at the pictures in the first post of this thread, specifically the Eiger clip. It attaches under the threaded momentary plunger, or keychain attachment. The hole, however, is a bit bigger than the size that would be needed for the 1/4-20 sized bolt that would facilitate attachment to a Titan or Tasklight. A smaller hole in the clip would allow secure attachment to a Titan, allowing my favorite SF to be clipped to my pocket, where it belongs. Perhaps if enough interest is there,, some clips in the next run could be made with the smaller hole... Never hurts to ask and see if there's interest!
