    In response to Lagrangian

Some useful information regarding the Sharpmaker rods from Pam:

Lagrangian, thank you for digging deeper into the grit grading standards. It is clear from the wide particle variances that a strict bijection is impossible, but unified charts are still useful guidelines.

Komitadjie kindly sent me the chart information. I would like to present it in a few new forms. They are a "Mr. Magoo" table, a line chart, and a chart with names placed logarithmically by micron size. I hope that they will be helpful in referencing this data.

I omitted a few data points from the two charts for clarity. On the first one I left out the EdgePro #2000 tape as it is wildly off the trend line. On the second chart, I removed the 10K and 16K Shapton stones, and the JIS 180, because they overlapped other names. Neither chart preserves the "approximate" and "compound" labels from the table.

I welcome any suggestions for improving these.
