I like these. Good solid construction.
Size: 10-pc, Color: Black/Stainless Steel, Size: 10-pc, Color: Black/Stainless Steel
It was past time for new knives. My old set Revereware was way over a dozen years old. One of the handles had broken years ago.
One of the best parts of these is the full length of the blade running from tip to end of the handles ( full tang ). The blades of my old ones of went about a half inch into the handles.
The blades are about the same thickness. Overall these Henckel's knives are much nicer. I especially like getting the carving knife. I have used that a lot over the years. Both of the scissors are China made. All the Henckels knives say made in India. The Revere knives all say China.
I washed them all up. They all shine really nice and the handles are comfortable. I'm happy with them.

Return policy stinks/decent starter set
Size: 12-pc, Color: Cherry
This is a decent set of what I would consider to be starter knives. We purchased a set for our vacation rental home and a second for our son when he was moving into his own place. They are basic knives that you could get away with if you aren’t doing a ton of cooking but you would probably want to fill in with a few other utility knives, as I did even for the rental, if you cook daily. They seemed sharp on the first few uses but they don’t hold the edge so maybe the steel isn’t the best quality. The real reason for three stars is due to the return policy from this seller. We accidentally ordered two sets for our son and the return shipping cost is a good percentage of the purchase price; it’s not like most Amazon sellers who have free returns. We ended up keeping them rather than lose money because we figure we will need to replace them soon.

Good value for money and a reliable set
Size: 12-pc, Color: Cherry
It is a great knife set for a first timer to own. I cook quite a bit and it is helpful to have a set of knives that can get the job done. I like the steak knives as well. They will come in handy when we have guests for dinner.

Fantastic build quality, fantastic price
Color: Cream White
I needed something fast for a chicken and dumplings recipe. Everything in store was outrageously expensive for the size I needed. Got on amazon and found this guy. Nice and large and build quality is excellent. Zero imperfections in the enamel. Heats evenly and is a dream to cook in, nothing sticks easy cleaning. For the price (about 50% less then anything in store) was an absolute deal. Highly recommended.
Just a heads up tho...this thing is heavy. I dont think its heavier then a similar sized enamel cast iron dutch oven tho.
