One thing is for certain, the SandFlex Abraser is no ordinary sanding sponge. SandFlex Abrasive Blocks are made of a unique rubber compound that is impregnated with abrasive throughout the entire block. As it wears, it constantly exposes a fresh abrasive surface, self-cleans and self-sharpens. Use it like an eraser-simply rub firmly. The sanding blocks can even be carved and shaped to match contours such as for moldings or for turned bowls. They are ideal for polishing your cast iron power tool tables, chisels and plane blades, and they make incredibly quick work of shining up a stainless steel sink!

Features:
  • Won't dull or clog
  • Can be used wet or dry
  • Fine grit is roughly equivalent to 240 grit
  • Medium grit is roughly equivalent to 120 grit

When others move your tools they don't think about the care you put into them. Rust is a pain to get off but this really does the job.

Better order two!
I ordered the fine grit one to keep my WoodRiver and Lie-Nielsen tools fresh and bright. I found myself using it to clean and brighten everything. It worked wonders on my combination square rules. Also for my table saw table just taking the little dingy look out of it..

I wouldn't suggest this on the brass backs of saws. That's pretty soft and might cause some pretty deep scratches

Despite keeping my prized Lie Nielson...
Despite keeping my prized Lie Nielson block plane clean and oiled, it developed some very light rust on the sides and sole. I tried 1000 grit sand paper first which removed some rust but left a dull finish that didnt match the factory polish. I ordered a fine Sandflex blocks, and they worked wonders. It looks just like new and the blocks should last a very long time.

I saw on YouTube how to clean garden tools, this sand block was used. It seemed effortless to clean the goop off of garden shears, and that is what I need, easy! So I chose what she was using.

It has grit all the way thru the sponge not just on the surface. I was a little upset that it is so small.

These blocks work well for sanding cabinet pieces. Allows more contact with the wood.

Is there anything metallic in the grit? My concern is whether or not fine metal particles will be picked-up by motors.
imREH on May 9, 2016
BEST ANSWER: Hi imREH. Your concern applies to any grit, metallic or not (and magnetic or not). In fact the non-metallic grit is much harder than the metallic and will do more damage to knives and machine surfaces. As for motor damage, motors in your shop should all be factory sealed and dust proof. Your bigger induction motors are probably explosion proof. Dust will not reach vital motor parts.
is this the product that is very useful for sanding turned legs but disintegrates as you use it? It conforms to the turning but doesn't last very long if you are sanding a lot of turned legs
Barb S on Oct 13, 2015
BEST ANSWER: Barb, this is not made for sanding turnings. I suspect the heat would melt the bonding agent. The fact that it is flat and complies very little to the sanded surface would not make it appropriate for turning applications. Instead, use cloth backed sandpaper, in sheets or strips. I use this product very sparingly to rub out tough stains on flat machine surfaces (like table top surface). The nice thing about it is that it frees new abrasive particles as it wears.
