I may be off target, but what about sewing the shieth to the outside of the pack. You could reach over your head to draw it out. Returning it to the shieth would be a hassle, as would be times if you fell on your back. But depending on how you intend to use the knife, that might not matter.<br><br>For splitting wood and other heavy duty cutting chores, you are not likely to have you pack on anyway. An external shieth allows easy access without having to rumage through your gear. In an emergeny, your multi-tool and/or pocket knife should be easily retreived from your non-BSA <S> cargo pants pocket.<br><br>Of course, if you anticipate a a situation where you may quickly end up sans pack and want the fixed blade in ahurry, none of these ideas fit. But it would seem to work well with the Boy Scout aspect.
