Shape. As you might have guessed, round particles are less abrasive than coarse ones. The sharpness of angles in a particle determines how deeply it will cut into a metal. A sharp particle will dig farther into a metal surface than a round particle of the same size. The four categories of shape are angular, sub-angular, sub-rounded and round.

Reloading: Sierra V-Crown Redefines Hollow Point Bullets
V-Crown bullets are a new design, and most of them have a distinctly different shape than Sierra's traditional line of JHP bullets. Traditional Sierra JHP bullets have a truncated cone nose shape, whereas most of the V-Crown bullets have a curved nose. The exception is the 90-grain .355-inch bullet, which retains the conical nose shape.

What is Grain Size? How is Grain Size measured? - Geology Page
In typical rivers the largest carried sediment is of sand and gravel size, but larger floods can carry cobbles and even boulders. In a stream, the most easily eroded particles are small sand grains between 0.2 mm and 0.5 mm. Anything smaller or larger requires a higher water velocity to be eroded and entrained in the flow.

4.) Flaky Aggregates - The aggregate is said to be flaky when the least dimension of aggregate is less than 3/5th (or 60%) of its mean dimension. Mean dimension is the average size through which the particles pass and the sieve size on which these are retained. For example, mean size of the particles passing through 20 mm sieve and retained on 16 mm sieve is (20+16)/2=18 mm.
