Usually only found in machine shops, the super flat face of the granite surface plate is ideal for leveling small plane beds, flattening waterstones and general sharpening duties. Simply soak a piece of wet/dry sandpaper in water and lay it down on the stone; the capillary action of the water adheres the paper to the stone, eliminating the need for spray adhesives or PSA sandpaper. When done, wipe clean with a paper towel. This A grade plate measures 12" x 18" x 3", weighs 80 lbs. and comes with a surface map. Plate does not have ledges.

    Any serious woodworker needs a granite s

    I have had one of these granite slabs for about 10 years. I can't imagine how anyone could not use one of these on a daily basis for tool sharpening and touchups. The only downside is the weight but long ago, I built a table/stand for mine. Under the table top, I have several shelves that hold all my Japanese water stones, sharpening papers, etc. Just get one, you won't regret it...

    Excellent value!

    Using this in my small machine shop as a flat reference for precision measurements. It is as flat as the 4' x 8' x 1' Starrett granite I use for CMM measuring at work.

    Excellent Value

    This is an excellent value for a decent sized surface plate. It has the the disadvantage of being heavy, but as long as you don't plan to move it very often, that's a feature, not a bug

    Flat out this thing is awesome!

    I needed something that I knew was flat for sharpening various tools and truing planes etc. This couldn't work any better! It comes with a certificate of accuracy and flatness so I know this is flat. It works like a charm and wish I had bought it much sooner.
