V, top and bottom are ground. The ends are finished and slightly rough. Two edges are machined and slightly rough. In my pair, the Vs match well, the top and bottom fit between the two blocks within my ability to measure (less than 0.001 inch). The paint is rough, the rough surfaces are a bit rougher than I could have been. expected but not a real problem. These aren't the best blocks, but they are more than I expected for the price.
