Japanese Rust Eraser Block #320 (Sabitoru MS-47)

Your knife didn’t show up to the kitchen to die in a drawer. It’s not a museum piece. It’s a tool. But even the best tools rust—especially high-carbon steel. That’s why this little grey block exists.

The Sabitoru MS-47 is Japan’s answer to surface rust. It’s a fine grit #320 rubberized abrasive block that acts like a pencil eraser—only instead of fixing math mistakes, it fixes your neglect.

Rub it dry, use it wet, or team it up with a bit of dish soap for stubborn spots. Safe for knives, respectful of patina, and just rough enough to knock rust down without grinding your edge into the Stone Age.

Used by pros in Japan. Now sitting on your counter. (Or should be.)

Works great on:

• High-carbon Japanese kitchen knives

• Collector blades you pretend aren’t sharp enough to use

• Rusty spots on your sink, bike, or your conscience

Proudly Made in Japan. No nonsense. No rust.
