Premium Rust Remover & Eraser - Knife Maintenance and Care - For Knives, Scissors, Stainless Steel Pots and Pans, Whetstones - Sharp Polish for Tools - Calcium Carbonate

I used on some fixed blade that sat in their sheath too long. Cleaned them up good, im happy and recommend it.

This is, by far, my favorite way of getting rust off scissors and knives. It will slightly etch the metal, so definitely rub off the rust along the grain of the knife or scissors. I've tried the products that have you soak the knife, scissors or tool and, although they work well, nothing beats the convenience and ease of this product. Soak in water for 5 minutes, wet down the rusted item and the rust comes off easily with a little bit of elbow grease depending on how rusted the item in. I could not be happier!

I used the block on my carbon steel kitchen knives and it works well I would buy again

Absolutely love this eraser, it's incredible, I soak it in water for 5 minutes, then just rub it on any of my utensils, and the rust comes right off

I restore and sharpen knives and this is a great product. Scours but doesn’t leave behind marks. Highly recommend.

I use this on my axes and hatchets to remove rust from the heads on each prior to sharpening them on my edge pro inc sharpening system. Make’s quick work of rust

Used with my Battle Sword. The product claims to be a rust remover, yet I find that it doesn't work very well for that at all. Regardless of what solution I pair with it in its usage, there are always better options. Maybe I just haven't found the right product to pair with it? I wish people could respond to Amazon Reviews. Otherwise, I believe that this is for delicate, light-duty use only. Other than that it is a cool block and I appreciate it's Japanese origin.

Don't let the picture fool you. This thing is tiny. For that price I was expecting something 3 times the size. Yes it did work great. I had a quarter sized rust spot on a hand plane and it took it off. There was still a mark there but the rust was gone.

Lo utilizo para limpiar las piedras Japonesas de afilar que son cerámica y hace un buen trabajo desde 400# hasta 12 000#.

Excelente producto para quitar el oxido a tus cuchillos. Es fácil de usar

I was surprised that this worked as well as it did. Someone in my house had left my new santoku knife in the sink with bleach spray all over it. This little block got rid of the small amounts of rust and didn't scratch it or rub off the logo on the knife when I had to go over that. Just this, water and elbow grease is all it took.

Holly Molly!! Works like a charm. Rust gone. I bought this just to try it, I thought it was BS but it works. Much smaller than I thought it would be though.

Worked very well on some rusty carbon steel knives
