Off hand tools still useful?

I think Kaeko or some other statistically minded soul proposed the conclusive test, it involved synthing things at the highest level difference you can reach (being 10 below the recipe) and recording results with various setups of stats, probably impossible to get a decent set of data before level 20, and I don't really know how much you can really focus on one crafting stat or the other before you get to the "non hobo" gear levels.
I just toss it and keep everything on a relatively even plane, balance all three as best I can.

Thank you for the replies everyone. I had asked because bestides level gaps where the stats we're better then my main tool. My inventory space needed some relief. And i hoped i could make some extra by "retireing" some offhand tools.

Since i'm still working my way up my current MH tools seem to be doing a fair job. I'll keep all the info in mind as i move to more difficult items.

Thanks again!
