Leather thickness is approximately 7 – 8 oz. The whole case is only one piece of leather bound with heavy duty copper rivets. It comes conditioned with natural leather conditioner made of beeswax and other oils. It is recommended that you apply leather oil or conditioner periodically to keep the case soft and water resistant. The leather may vary slightly in color and how much it stretches. Your Gerber should fit snug right at first, but will wear in to fit comfortably. Made to fit Gerber MP600. Inside Dimensions: 5 1/8″ x 1 1/2″ x 5/8″ For belts up to 1 3/4″ width. Handmade In The U.S.A. If you would like a custom case made to a different size or color, please contact me and I will be happy to try it for you!
