Review on Nicholson Hand American Pattern Rectangular Abrasive & Finishing Products: Quality Tools for Precise Finishing Applications by Larry Long

Thanks to my knowledge gained in practice, I can say that this product is not worth buying. Despite being advertised as suitable for industrial and scientific use, it falls short in its performance as a finishing product. The abrasive quality is weak, leaving rough and inconsistent finishes. The only positive aspect is the rectangular shape, which can be useful for certain applications. Save your money and look for a more effective abrasive and finishing product.
