Even with hand washing, the silver finish on the handles has worn off, so your hands are black after use. Just bought these a couple months ago, only use once or twice a week at most.

Hi Amy,
Thanks for contacting us.
Oxidation on aluminum handles is most often caused by the abrasive detergents, high temperatures used in a dishwasher, as well as if left in wet conditions. When oxidation occurs, aluminum may appear dull with a gray or black residue. This is merely a characteristic of aluminum and in no way affects the durability of the handle or the performance of the knife.
If your knives have suffered from oxidation, you can use a cleanser such as Bar Keepers Friend. Using this product as directed will help return knives to their pre-oxidized condition.
Hand washing all fine cutlery is recommended to protect your knives from corrosion and extend the life of their finish.
while they work very well, I was disappointed when they were put in the dishwasher by my mom who is living with us. She is elderly, sometimes forgetful. So the discoloration is very noticeable.
wonderful however i do not see a fillet knife no serreated

Hi Fay, Thank you for your review on your Rada Cutlery. We have discontinued our fillet and sportsman knife, therefore these are not available. We hope to possibly bring back these knives in future, but have not definite timeline at the moment. Please check back on our website for more new items coming August 1st.
