Way Awesome as my grandaughter would say.

These are great blocks especially for arthritic hands. This was a replacement block for one that broke. Hassle free warranty replacement. I plan to expand my collection of Linear Block products as my budget allows.

Nathan G
Awesome product

I had a issue with one of my blocks they sent me a new one fast and great to deal with. The block makes 180 sand like it's 80 grit. Wish I would have looked into them sooner. There is a learning curve keep that in mind when you get them.


It's a great blocking tool.. It does good work.
