The last Kanji on a Date Mei

[Itomagoi]

Excuse me, but what does the last kanji here mean? I just can't figure it out. 

Showa Go Nen Sho Gatsu X?

[Shugyosha]

Hi Peter,

I think kitau - 鍛 "forged".

[Itomagoi]

Hi John, 

ah okay. Forged on a day in January in the year Showa 5 (1930).

Thank you!
