Tender's 'Bronze Wire Buckle' belts are cut, sewn, and gold foil stamped by hand in England, from brown stained leather tanned for 18 months in England using oak bark liquor. The buckle is lost wax-cast in England from solid bronze, using a caster's pattern hand constructed in England.

The 'wire' buckle was the first buckle in Tender's collection, and is an experiment around the idea of a standard pin buckle. A normal pin belt buckle has the pin mechanically bent over the box. As Tender's buckles are all solid cast, this is no good, because bronze cannot be safely bent into shape after casting. So instead of a box and a pin, the Wire buckle consists of two interlocking continuous wires, which fit together easily, and are held in place by the belt itself.

Prior to the launch of the Trestle Shop, all of Tender's belt buckles have been cast in brass, an alloy of copper and zinc. This buckle, however, is cast from bronze, a similar alloy but with a higher copper content. The extra copper gives bronze a slightly darker, pinker, cast, and over time it will patinate darker than brass does. 

Tender's belts cut from this brown stained oak bark leather are also available with 'Keeper', 'Stud', and 'S' buckles, and on black leather with a bronze 'Hook'. 'Loops' belts are made with cotton webbing. Wattle-tanned leather wallets are made unstained or hand-dyed with black logwood. To keep the leather supple and in top condition we recommend using pure mutton tallow Boot Grease.
