I just completed a leather tool roll for someone who has really helped me hatch out ideas and get this little business going. You can call him my boss. Something special was in order. It has seven slots (instead of the standard five), is personalized with his initials on the upper strap and is able to be 'tied' to close using adjustable sliders. I even purchased a one of a kind piece of leather to get the dark, oiled look he was after. Take a look.
You can see more small and large wool felt and leather tool rolls here.
