3 Pcs Gummy Rubber Abrasive Stone- Edge Grinding Rubber Block Stone- Soft Snowboard Gummy Stone- Snowboard Ski Stone for Removing Rust and Burrs (Blue 60 Grit, Green 120 Grit, Red 240 Grit)

Great product! They worked really well and the price was great.

Bought it to remove some rust on the edges of my skis, and they worked really well! Would recommend especially for the price.

Cleaned the rust spots and smoothed the slightly uneven surface of my skiis. Very quick and easy and well worth the money.

Works very well for removing rust off skiis

I love this Watayo product although I was only able to discern slight differences in grit between blue and green. I have used both blocks on my feder and on my Hanwei Rhinelander bastard sword - seen in the photos, above.Both blades have some pretty significant burrs and the blocks did not suffice to remove them. Both blades were used when I got them and had some rust - the blocks cleaned up all but the most pitted rust spots - and rust removal is an ongoing thing with steel blades.I like that the gummy blocks polished the steel as opposed to scoring it as did the 3M block. Compared to a 3M 180 grit sanding block, the 3M product felt grittier than either the blue or the green gummy block and produced rougher looking results, but that was an apples to oranges comparison as the blocks are made for different purposes and vary in composition.Update: I tried the blocks out on my EDC knife that'd gotten scuffed and tape goo stuck on it from frequent use as a box-cutter, pry-bar, etc. Cleaned it up beautifully. Very pleased.

Worked perfectly!

As advertised. Fast shipping.
