Rectangular Belt Buckle with Concave Edges, 1450–1600

Late Gothic Double-Rectangular Brass Belt Buckle with Concave Edges, 1450–1600

History and Origins of Double-Rectangular Buckles in the 15th and 16th Centuries

The historical design of this buckle is based on archaeological finds dated between 1450 and 1600 (Late Middle Ages to Renaissance). During this era, metalwork for clothing and armor evolved noticeably—straight-edged rectangular buckle frames gave way to elegant concave contours and architectural corner elements.

Double-loop rectangular buckles featuring central pin bars and concave sides were highly sought-after fasteners across Western and Central Europe in Late Gothic and Renaissance times. Historically, buckles of this style fastened men's and women's dress belts approximately 25 mm (approx. 1.00 in) wide worn over doublets, gowns, or gambesons. They secured pouches and dagger sheaths, and formed a vital component of armor harnesses—fastening helmet chin straps (such as on sallets or burgonets) and leg harness straps. The molded corner plates provided visual appeal while reinforcing the cast frame under tension.

Mounting and Assembly Instructions

Attaching this Late Gothic buckle to a leather strap is straightforward and easy to accomplish in your workshop:

• Prepare the Leather: Select a leather strap up to 25.00 mm (approx. 0.98 in) wide (ideally 23 to 25 mm / 0.90 to 0.98 in). Punch a longitudinal slot near the end of the strap for the buckle pin.
• Position the Pin: Feed the buckle pin through the punched slot so it sits freely on the central crossbar.
• Secure the Strap: Fold the leather end back around the central crossbar and secure it tightly with heavy waxed thread, brass rivets, or a metal strap mount.
• Fastening: Thread the strap tip through the first loop, insert the pin through the desired hole in the leather, and feed the strap through the second loop so the pin rests against the outer profiled rim.

Care and Safety Instructions

Cast brass is a very durable metal requiring minimal care. To keep your buckle looking its best, observe these simple guidelines:

• Wipe dry with a soft cotton cloth after exposure to rain, moisture, or sweat.
• Avoid harsh chemical cleaners or abrasive polishing pastes, which could strip away the dark antiqued patina or silver plating highlighting the corner detailing.
• The pin point is functional – handle with care during assembly and wear to avoid scratching leather or skin.
• Do not subject the buckle or pin to extreme bending forces.
• Keep out of reach of small children due to small parts.

Recommended Accessories

We recommend pairing this buckle with a 23–25 mm (approx. 1 in) wide blank leather strap from our store, a matching 15th or 16th-century brass strap end (chape), and brass belt rivets. It is ideal for belts worn over Late Gothic tunics, gambesons, doublets, helmet chin straps, or knightly armor harnesses.
