About Myojinriki Seisakusho 明神利器製作所 / Tetsujin Knife Labo 鉄人刃物ラボ

Myojinriki Seisakusho is a Kochi-based knifemaking workshop run by Tateo Myojin (明神 健雄) and Naohito Myojin (明神 直人), the father and son team. Tateo, who was born in the largely rural Kochi Prefecture in 1950, developed his interest in blade forging at a young age, so he went to Sakai, Osaka Prefecture, the famous city of forged knives, to receive training from Sakai knifemakers.

Tateo’s son Naohito-san - being a rebellion youth- refused to join the family business, until he sharpened his friend’s knife and received a compliment from his friends. The joy he got from doing it changed his mind, and he decided to be an apprentice under his father. Now just in his early 30s, Naohito already has over a decade of knife making experience under his belt. He has new ideas for the family business, and has recently launched a new family brand - Tetsujin Knife Labo (鉄人刃物ラボ).

Care:

Aogami #2 (Blue #2) steel is a premium Japanese high carbon steel for knife making. Despite some corrosion resistant quality (for a carbon steel), it is not stainless, therefore you should wipe your knife dry after each use. Patina will develop over time. Rust may develop if left in prolonged contact with water or acidic food. Use a rust eraser to clean if rusts develop. Avoid cutting into bones, frozen foods, hard fruit pits.

Cutting Surface:

Recommended cutting surface: wood, rubberized boards and high-end composites, and quality plastics such as polyethene make acceptable cutting surfaces, and will help protect and prolong knife’s edge. AVOID glass, metal, countertops, and other rigid, non-forgiving surfaces.

Sharpening:

We recommend sharpening all quality Japanese knives on whetstones, as we believe they yield the best results for your knives.

Best cold brew brewer out there
Color: Black, Size: 40 oz
One of my favorite purchases in a long time. This coffee maker is just a perfect size and it can be put in the fridge in any direction, on its side, on its top, whatever. It does not leak and it's very easy to clean. Just a superior product all the way around.

Great cold brew maker!
So far this has been a big improvement from a different brand cold brew maker I had. It is simple and easy to used doesn’t leak. The coffee comes out tasting great! It has a smart design that works well. It’s a great deal for how well it works. It is big enough to last all week but not take up to much space in the fridge.

Air gets trapped in the filter so it won’t fully steep
Color: Black, Size: 40 oz
Filter doesn’t let air out. It’s weird about all these positive reviews bc I tried cold brewing tea two times overnight but the filter holes are so small that basically it traps a large air bubble inside with the tea leaves. The water was barely steeped. It was weird enough to the point where I thought there must be a clear film on the filter that I hadn’t removed. When I loosen the lid all do the air rushes out and it fills w water, but when you tighten the lid any air inside with your grounds/leaves is trapped and prevents steeping. I kept thinking it was me based on all of these positive reviews but I could not prevent the massive about of air from getting trapped in the filter. If they made the holes bigger (not too big to let grounds out but currently you could mistake it for plastic film) then it would’ve been perfect. Nice size and about what I’d drink in a day or so. Change the filter hole size to let air flow out and I’ll buy it back!

My tea stays warm to the bottom of the cup!!!
I am so glad I purchased this mug water. I drink tea all day but it cools down quickly. Since I purchased this mug warmer my tea stays hot to the bottom of the cup. The temperature is adjustable so you can keep your drink at your desired temperature. The top is glass and wipes clean easily. I like the rubber gasket that fits on top of the warmer. It keeps your mug in the center of the warmer and should you have a spill it catches the liquid. I've been using it every day for over a month now and it's going strong and is reliable. Perfect for personal use or as a gift.
