Care:

Aogami Super (Blue Super) steel is considered the most superior Japanese high carbon steel for knife making. It is not stainless, therefore you must wipe your knife dry after each use, in particular the core steel not covered by the stainless cladding. Patina will develop over time, which will appear as “discoloration” on the cutting edge, but that is the nature of carbon steel - not a defect. The stainless cladding covers a large part of the blade, making maintenance easier but still preserving the cutting and sharpening pleasure of the Aogami Super core. 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.

COOL Pillowcases Worth Buying
Color: Champagne, Size: Queen
I bought these to try out, and I was shocked to find they worked out better than my silk pillowcases. I have atopic dermatitis, and I need a pillowcase that doesn't irritate my skin. I also am having hot flashes and need something cool on my face. These pillowcases are perfect for both my conditions. I plan to buy more in different colors. My sons and husband also like it since they are always hot.
