Yes, I always end up making some up without the pouch as some folks like the sheath to have clean lines. Pouch can be handy though as can carry a sharpening stone or a Doans Magnesium firestarter kit as they are the same size.
Personally, I like having a pocket stone with me. Guess one could always be carried in the pack though....as long as you keep the pack with you. <img src="/ubbthreads/images/graemlins/blush.gif" alt="" />)

They say your memory is the second thing to go...I forget what the first thing is.
