Great knife set
Size: Ivory Series 15Pcs 14.43''×9.36''×6.63''
Overall a great knife set. Well built and craftsmanship, excellent sharpness (we’ll see over time) great looks and value. Would have liked for this color to be available in the bigger set of 8 steak knifes. Word of caution with this or any other knife set, DONOT PUT THEM IN THE DISHWASHER OR LEAVE THEM OUT TO DRY! YOU MUST CLEAN AND DRY THEM AFTER USE, If not they will have water spots which will be hard to remove or worse they’ll get rusted.

Very nice knives for the price, with additional options in the same pattern!
Size: Steel King 15Pcs 10.4"×7"×15.4"
It’s been 10 months, so I feel like I can finally give a decent opinion on this knife set. First of all, I really appreciate how sharp they are out of the box. The set of different blade shapes suits my needs quite well, with the exception of the bread knife, which I swapped in the block for Brodark’s deboning knife. I also added their breaking butcher knife, cleaver, and brisket slicer to my collection, all which match the handle style for this set. (I really liked that I could get the same pattern for some additional blades to expand my kitchen set without getting a different pattern.) The knives should never go through the dishwasher - I tested with one of the steak knives and water spots rusted lightly. I was able to buff the stains out, but the “high carbon stainless steel” is definitely as described. When used normally I do soap and water cleanup, dry, then back in the block without issues. I have honed the chef and slicing knives so they glide through food more easily, but they retain their edges well enough I haven’t needed to repeat the process in normal use. The block is quite heavy and very durable, but still has a rather compact space use as it stands pretty close to vertical. I have mine pulled forward on the counter as our cabinets are rather low, and there is no hint of instability when drawing or resheathing blades. The finish is quite nice, and no need for touchups or worry about the blades wearing in the slots like softer wood blocks can have happen. All the blades fit well in their respective slots. You do need to grip the handles by the ends to draw some of the blades as there are a lot of tools in close proximity, and my fingers and hands are large. I got my set last Black Friday. With the prices and discounts that keep popping up, you could still get a pretty good price most of the year. If you want the option for additional knives of similar handle pattern, do a quick Amazon search for ‘Brodark knife’ and check their options. There have been a lot of good spot sales lately!

Very nice knife set.
Size: Steel King 15Pcs 10.4"×7"×15.4", Size: Steel King 15Pcs 10.4"×7"×15.4"
Got these as a Christmas present and they are a very nice set of knives. They are very sharp so be careful when taking them out of the little sleeves they come in. The wooden base is surprisingly heavy and does a great job at holding the knives without sliding around. The built in sharpener works good to fine tune the edge with just a gentle pull through the ceramic side. They also come with a lifetime warranty which is nice.

Great Knives
Size: 12-pc, Color: Gray
These are great knives. Sharp as can be. Be careful. Wash delicately & don't put them down point first in dishwasher. Lay them down flat. The point is sharp and could bend or get bent. Point is sharp as hell and thin. But very hardy strong knives
