Rust Eraser Sabitoru Medium and Fine 2-piece Set

I'm incredibly impressed with its performance. I've tried various methods to remove rust from my knife blades, but nothing has worked as effectively as this product. The erasers effortlessly eliminate rust, leaving my blades looking brand new. The medium and fine grits offer versatility for different levels of rust, and the results are truly remarkable. If you're looking for a reliable and efficient way to remove rust from your knives, this set is a must-have.This review represents my personal opinion and experience with this product.

I got these in today and was excited to try them on my shapton glass and rockstar stones. I soaked the fine one for a bit over ten minutes but they only had a few bubbles when I first put it in and that was it but I left it in anyway. With only the first few strokes I was able to see and feel my stones getting nice and clean. I finished cleaning them, rinsed them off really good but didn’t touch the ceramic sides, and then left them to dry. I was surprised how awesome they felt once dried, they are completely smooth and perfectly clean. I didn’t see anything come off of the erasers, just white ceramic from my stones, and I’ve already been told these can last for years. At only just over $5 each these are an excellent addition to my arsenal. I’m going to use the coarse eraser for my whatever a high polymer eraser can’t remove from my diamond stones as I’ve been told these work great for that too. Not to mention the intended purpose of being able to remove rust, these are just so versatile, effective, and cheap. It’s great to find such awesome products like these little gems.

Great little product. A must for the workshop. I wouldn’t use on highly polished cutlery etc but for garden tools, chisels, and other shop blades it does great.

I received this and since I can't read Japanese I had to feel which one is fine and medium. Fine = red lettering. Medium = white lettering. The medium works better than the fine on knives. I've used them on my Norton IB8 sharpening stone to remove surface build up, neither worked well probably because the stone is coarse with a 100 grit side and 320 grit side. The fine eraser works good as a pencil eraser (not kidding). I've tested it on paper. I will be using the medium eraser in the future to remove rust on other metal tools that I have. I've seen videos and people have been able to use this to remove build up / load up from sharpening stones but they have a much higher grit than I have.

I can sing no higher praises for these. They work! It's like literally erasing rust. I've used these on several small restoration projects and it's amazing while ready for lots moreNot too abrasive, with sufficient time and elbow grease you will erase the impurity from the metal. I've even touched up a couple of edges with these, when they require a very fine abrasive for the most minor of corrections. Sustained use does a suprisingly good job of actual reshaping and sharpening small parts of the blade when done carefully and right, tho still not as good as actual tools for that purposeI even used to hate the eraser these are based on, for actus writing, because of how they felt in the hand and the sound they made plus their texture, even their smell. But these rust erasers don't even have any of those minor annoyances wrong with them. I literally can't find a single negative thing to say about these, except that not enough people know about such a marvelous invention!

They're soft, just like an eraser and do they ever work! I bought medium and fine.

Excellent for cleaning diamond sharpening plates, you only need the fine grit and I recommend using eraser, alcohol wipe and repeat with eraser.

Works like magic. Great value for the price you pay.
