I have a leatherman supertool, I bought the nylon sheath for it that holds a mini mag flashlight, the one that has 2 double AA's, but what flashlight is there, that is basically the same length, takes the same size batteries, but is built heavier duty, brighter, and must fit in the sheath, I dont know to much about lights, but I would like to stay under $50.00, any help would be appreciated, thanks..
