3M Rubber Sanding Block, 2 5/8 in x 4 3/4 in x 1 1/4 in

This solidly made hard rubber product should last for a very long time. An unexpected benefit is that the heavier weight makes it easier to use because I find it works beautifully without me having to use a lot of pressure. I’m currently using it with 80 grit on raw stock, and it works great!

Works great!

Works wonderfully. The rubber is a bit too hard on first receiving to easily get the paper inside however it does loosen up with use and heat. Biggest con is the size. Due to the smaller base size and how much paper you need to attach it to the nails you end up only using about 50% of the strip of paper.

Typical block style! Have had many over the years. They work good for about a year then rubber starts to harden and then the crack or get so stiff you cannot work with them to load paper.

Good for small area.

Works good for sanding

Solid...that is the word I give this.

I wish there was a trustworthy brand that made something more lightweight, but all the reviews (and my experiences) suggest anything cheaper either will fall apart or is somehow not flat on the bottom (and so can't do the only thing a sanding block needs to do). So that leaves you with this classic brick. I don't understand why it needs to be so heavy, as that gets in the way of being able to use it more effectively and for longer periods of time. Also, the process of opening / removing / replacing the paper seems to take three hands, so unless you have a close assistant helping you sand, then you'll have to figure out how to do it "good enough" with just two.
