Chukyokenma, M Rust Eraser, Sabitoru

Works very well on garden tools, was pleasantly surprised. Ive previously used sandpaper, but this does the job without the abrasion

An indispensible little thing you'll never know you needed! I've been using this clever little thing to remove rust and oxidation from all sorts of steels; high carbon, stainless and others, it's made an easy job of all of 'em!

Smaller than ideal, but works well on rusty knives and blades if you soak on water for about 10 minutes beforehand and apply plenty of elbow grease.

Excellent for cleaning surface rust from secateurs , garden knives etc. good value

I wasn't holding out a lot of hope, but it actually works! Dissolved the rust of the blades of my shears really well.

I lost my Crean Mate and needed a replacement. They’re very expensive now, this isn’t and while it’s slightly thinner than the CM it works exactly as well. For the price I am delighted. It keeps my nice secateurs blemish free. Recommended.

Great little stone, revealed the shiny metal underneath all the ingrained dirt as per the before and after photos above. Can be a little tricky to get into corners but you can literally use it like an eraser, ie just use the corner of the stone and rub away the dirt as if you were removing pencil from your school notebook. I wet the stone and the metal before using, then dunked the tools in water after rubbing, before drying off with kitchen towel and oiling.

Instructions are in Japanese. So OK if you can read it, but useless if you can’t, like me. I don’t think Amazon should sell any product without user instructions in clear English
