Design me a Product

Design me an EDC (everyday carry) pocket organizer. It should look modern and sleek - intended for office workers and businessmen to carry around in their suit/pants pocket. Materials considered include leather, synthetic, fabric etc. It should either come in different sizes or expand to fill someone's pocket. It should have some sort of elastic/strap system to store different items: pens, keys, torches, knifes etc. The final design should have specific dimensions which a manufacturer can follow and create. Knowledge of different materials and good fashion sense essential.
