Irons without offset

If you want a set of mens left-handed irons completely without offset, are one of your few options Wilson Staff FG62 Blade Irons ? Are there any other forged set of irons which have these properties? It's really hard to find an i1 (one iron) completely without offset. (They have to be made of carbon steele so I can adjust the lie.)

Why are they called Zero Offset when there's a 1.75 mm offset for the 1 iron?

Probably because the offset is the same from the 1 iron to the 7 iron, then the same from the 8 iron to the gap wedge (although .5mm/.020" difference separates the 1-7 from the 8-GW)?  I can only guess when they say "zero offset" they are referring to the fact that the offset remains consistent through the longer irons, versus heads that are progressive through the set..... 4i @ .180", 5i @ .160", 6i @ .140", etc., etc., etc.  FWIW, a 1.75mm offset is about 0.069".

If that Wilson set had a 1i, it looks like it would be about .101".2.57mm (0.0762mm/.003" difference head to head).

It seems like none of these iron sets exist in mens left-handed versions iron 1 through PW. Which set, available in mens left-handed versions iron-1 through PW, have the least amount of offset? Preferrably forged and with a sole which is not too wide (like a blade).
