Buckle type attachment elements, such as for belts, watch bands, or the like, and/or for securing or fastening elements (e.g., for footwear, handbags, briefcases, containers, or other objects) may be produced in a manner that generates minimal waste materials, without the use of metal or mechanical hardware type connectors, from completely recyclable materials, without the need for molding, without the use of plastics, and/or without the use of adhesives or cements. Such buckle elements may include a buckle portion and a tongue portion formed from the same material. In some structures, the tongue portion may be made from a part cut out to form the buckle portion. In other structures, the tongue portion may be formed by cutting slits into a base substrate that also makes up the buckle portion. Final products and methods of making such products also are described.
