.Metal Precision Model: Based on the working principle of the Stirling engine, the balance Stirling engine runs fast with strong power only heated by the alcohol lamp. The safe, durable and all-metal engine model with a unique&novel shape makes a blockbusting fashion gift and personal collection for fans.


.Reliable Design & Operation: With innovative design philosophy, the whole engine is designed with boiler shape and the steam channel&baseplate adopt the integrated design for safety and durability. Working in conjunction with an alcohol lamp to heat and drive, the engine is capable of working continuously for about 30 minutes.

The surface will not fade for a long time due to oxidation treatment.

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

Better than what we were using.
Size: 7-pc, Color: Brown
I grew tired of going for a knife only to find that what we had were dull, pitted and bent tips. So I gathered them all up, sorted through them and threw the worst of the worst out. Discovered long ago that those expensive knife sharpeners don’t work either. So I purchased this set as a throwaway set. I’ll use them until they too have seen thier better days and then buy another set.

I wish there was an instruction manual
Size: 10-pc, Color: Black/Stainless Steel, Size: 10-pc, Color: Black/Stainless Steel
I chose this set because somehow other options out there involves more than 1 bread knife and less variety of other knives for some reason and I don’t eat bread. Also I know that this brand is a sister brand of Zwilling which my dad is a fan of so I’m pretty sure of the quality and the sharpness. When I say I wish there was a manual was because 1. I’m not a chef. Nor did I take up any culinary class, so I wish there’s at least a pamphlet in the set to identify which knife does what or what people actually use them for before I use everything randomly, which also works, but I’d like to use them correctly since I bought a decent set. And yes I know I can google it. Just saying would be nice if it comes with one. 2. I wish there was a direction for the block for which knife belongs to which hole. I am pretty sure that usually the blocks would have different depths and the knives come with different lengths. So it would be great to have that indication before I mess up the tip. All in all, it is a really nice set. It is sharp as the other reviews mentioned in their videos. Do handle with care and don’t cut yourself when you’re unpacking them. Knife is sharp.
