2 Dated recipes: Iron Poleyns to 40 then at 40 do iron greaves, level 50 synth.

Iron Poleyns: Iron Square x2, Buffalo Leather Strap x1
Iron Greaves: Same as above

They may be a lot of shards for synths, but it really isn't that bad. I thought it was, but once you do it it isn't bad. You can hasty hand the iron squares. You get x12 iron sqaures for 3 iron nuggets. I bought like 3 stacks of iron nuggets and got about 7 stacks of squares. The straps are a low level ltw synth(21), one buffalo leather gets you x12 straps so its nice also.

Hope this helps.
