Radaknives4u.com will replace any products manufactured by our company returned to us due to defects in material or workmanship. Like all fine cutlery, please protect the cutting edge of the knife by storing the knife carefully in its gift box or blade sleeve. We recommend only washing our aluminum handle cutlery by hand and drying it immediately. Our stainless steel resin handle cutlery may be hand washed or placed in a dishwasher. Proper washing and care will maximize the beauty and performance of our cutlery.
