I ordered this set of knives as I'll be doing a lot of camping this summer and didn't want to bring my expensive Henckles with me and take the chance of losing them. So, after looking at customer reviews and listening to You Tube's "life regenerator" talk about how he loves his tomato knife, I decided to order this set to take along with me. I love, love, love these knives. They are very sharp and lightweight. As with most other customers, I did cut myself a couple of times due to their extreme sharpness.
The different colors help me to easily pick the knife I want. And the plastic storage case, though a little bulky, keeps the knives from bumping against each other and becoming dull. I've only had the set a couple of months, but the knives are still sharp after daily use. These are the knives I consistently reach for while preparing meals.
Like I said, I've only had them a couple of months, so I'm not sure how long the knives will keep their edge. However, for the price of them, I don't think I could ever be disappointed with them. At this point, I don't have any negatives.
