Over the years, many people have published weapon charts. Most of them have had mistakes. This is the correct weapon chart and you should discard all others.

From the chart above find their deftness requirements. Use these values in the chart below (MH on the left, OH on the top) and the result is the deftness to use them together.
Examples: Suppose your scum wants to use ME in your main hand and LG in your off hand. Cross referencing, 5 on the left, 7 on the top, you'll see that the required deftness to use them together is 9.
MH\OH 3 5 7 9 11 15 3 4 6 8 10 12 16 5 5 7 9 11 13 17 7 6 8 10 12 14 18 9 7 9 11 13 15 19 11 8 10 12 14 16 20 15 10 12 14 16 18 22Caveats: In finding the values for this chart, there have been inconsistencies. The chart shows the value that we believe will always be well suited. Some warriors seem to be able to use weapons in both hands with lower deftness than the chart shows. So far, I have not seen evidence for a warrior requiring more than the value shown. Note that some values make little sense. (While you can use an EP with an off hand SH together with 10 deftness, you would still lack 5 points of deftness to use the Epee.)
