Frequently Asked Questions

What is the difference between deployant and butterfly? Butterfly is a symmetrical double-fold style. Deployant is the broader term for folding clasps; many people use the words interchangeably.

Can I convert a tang buckle to a deployant? Yes – many aftermarket deployant clasps are made to replace a standard tang buckle on leather straps.

Which clasp is most secure? Push-button folding or tri-fold clasps generally offer the highest security against accidental opening.

Do all metal bracelets use the same clasp? No. Fold-over, butterfly and integrated hidden clasps are all common depending on the brand and model.
