Arrived whole
Style: Tree Pattern, Style: Tree Pattern
I noticed several posts where the holder was cracked and damaged. mine arrived fine but it came inside a larger box due to other items arriving with it so not sure it that helped, for future buyers. We've been remodeling our kitchen for over 1yr and a half. Most of the items I have were passed down when my mother passed. The silverware I had didn't match and it drove me nuts. I finally was at the point I could afford to replace all of it. So tossed it all out when these arrived. These are nice looking, very strong and feel of good quality. I picked the hammered look and black since the colors in the kitchen are steel, black appliances and the cabinets are a blue with marble counter. We bought marble dishes and wanted something other than steel silverware. Though the black, at a glance looks like plastic silverware due to how shiny they are. But I am happy. #1 thing that sold me were the steak knives. Serrated knives in set like these are usually just four. The teeth on these are sharp and when I used one on a cold cooked chicken breasts it cut through nicely and shredded it fine without issue. Most sets are usually just four of everything. I have family members every who come over every so often and we would like to host friends once in a while as well. So we needed more than four which at times is hard to come by. I also wash my dishes by hand. I haven't used a dishwasher in 22 yrs, so when remodeling I didn't waste money buying one. So far with washing these by hand, I have had no issue. No rust or odd spotting and no coloring chipped. So would likely suggest washing these by hand if others have issues with them in the dishwasher. For the price, the quality and the quantity, that alone is a steal for me. I didn't care if the holder arrived broken or not. Even if it didn't have the holder I would pay the same and buy this set.

Good value
Style: Heavy Duty
Nice set. The storage tray is too small for 18” drawers and too big for 15” drawers. Could be trimmed to fit the 15” drawer without impacting functionality. Has steak knives and butter knives but the butter knives will cut any steak I’ve ever had. Salad forks seem small to me but none of my guests commented on it.

Kitchen finds
Style: Heavy Duty
I absolutely love the size, finish and sharpness of this set. There’s nothing worse than a knife or fork that can’t cut through a piece of meat and it’s tender: easy fitting grip and use. Dishwasher safe. I’ve already purchased a second set. lol
