Our products are guaranteed for a period of 10 years against any manufacturing defect under normal use (a table knife is used to cut, a corkscrew to unclog a bottle). Wear due to weather, misuse or falling is not guaranteed. The knives must be returned to SCIP with proof of purchase. To avoid unnecessary returns, thank you to send aphoto of the damaged product to contact@scipfrance.com, in order to make a quote for the repair.
