K&S is pleased to bring the highly regarded Tetsujin (鉄人作) brand to our customers. More excitingly, we are also among the first resellers to introduce you the Tanryusen (鍛流線) Blue 2 line. Tanryusen literally translates into "the forged wave line".

I think this pic below is self-explanatory: the Tanryusen features some highly visible forging cloud on the iron cladding, very similar to the much loved and elusive Shigefusa cloud. The difference is that, often this type of forging lines are found on knives cladded with old wrought iron, which are usually rare and expensive; in contrast, the cladding cloud on Tanryusen is formed by great forging and sharpening techniques of the makers. 

 

(the highly visible cloud on the cladding of the Tetsujin Tanryusen line, resulted from Tetsujin's masterful forging and sharpening skills)

In case you are not familar with the Tetsujin brand, it is a collabration between two friends and colleagues: Toru Tamura and Naohito Myojin of Myojin Riki. It is famously carried by Konosuke Sakai as a sub-brand

Blacksmith: Toru Tamura (田村 徹)
Sharpener: Naohito Myojin (明神 直人)

======

Naohito Myojin (明神 直人) is a young sharpener based in Kochi prefecture. While his workshop Myojin Riki Seisakusho is probably not as famous as the established brands from Sakai and Echizen, he is the sharpener behind some of the very famous knife lines in the industry; noteabley the Tetsujin brand and the 'Fujiyama' line by Konosuke. 

I think 'refined' is the best word to describe Naohito's work: while featuring proven cutting performance, his knife has some of the best finishes out there. The spine is nicely chamfered, choil is well polished. By engraving his name Naohito on to the knivves, you can tell that he must be really proud of his work, and I trust you will enjoy his knife as well.

Buy this instead of the ‘brand name’ one
Size: Twin, Style: Warm
Tl:DR: Buy it, it’s super cheap, better than the one I paid 2x the price for and soft as it can get, and it really is a ‘Winter comforter’. This review is going to sound like I got paid off for it but I actually didn’t. I bought another comforter prior to this one, paid close to double of this one and that the ‘on sale’ price, and it is trash compared to this Amazon basics one. Both claim to be thick warm comforters but I can literally stack two of the other brand and maybe they’d be almost as thick as the Amazon one. I only bought this one because the other ‘winter’ one I bought was so thin and flimsy I figured adding another ‘cheapie’ one might make me not freeze to death. As soon as I arrived I noticed that this Amazon one was WAY thicker, nicer looking, softer and warmer than the old one. Just to try it out I stacked both of them together to see if I wouldn't freeze to death like I was doing with the old ‘expensive’ one: five minutes in and I was sweating. That’s all it took, I immediately removed the duvet cover from the old one, switched it to the Amazon one and threw the old one somewhere where I couldn’t see the money I had wasted, and yes the Amazon was warmer and softer even WITHOUT the duvet cover. I’m probably going to get the light version for when fall hits and I don’t quite need the heavy one yet. Buy it you won’t regret it and hey it’s Amazon brand so if you don’t like it they’ll take care of you, but I HIGHLY doubt you won’t love this thing.

Great duvet insert
Size: King, Style: Light
Perfect duvet insert. I got a pretty expensive duvet to cover this and they worked great together. The fit was perfect and I didn’t feel like the duvet was smaller than its cover. This was a cheap option that keep us warm while not being too think. This product is also breathable and recommend if you live in a place that transitions from hot to cold often.

Great comforter, especially for the price. I put it in the dryer for a bit when I first got it and it became nice and fluffy. Perfect mid-weight duvet.
