i never had a eq i made that got me a -8 jump before, except for a common rock from superior(Sacred Wands Q_Q)
My guess is that the iron fine sword is also iron/wood/hard tissue. the result of the fail alchemy should be a rank 10 from 17 (-7 jump). But because there is no eq that has a base of iron/wood/hard tissue that is a rank 10, it has no choice to pick the next lower rank 9 which happens to be a iron fine sword.
i hope i explained correctly.
alchemy is hard...
Edit: You should try iron net boots + wolf tooth + propeller + iron net boots instead.
it is 100% guarantee to get rank 20/21 iron using superior.
