If so, how did you come up with the name?

My first iaito I named Utau Shizukani. Misspelled over the years. It meant Sings Softly, because it did. It and its successors Nihonmei and Sanbonmei (2nd and 3rd long ones), succumbed to metal fatigue right in front of the tsuba.

My sensi suggested upping the quality. Yohonmei has been singing beautifully for ten years.

No.

I usually refer to it as my sword. Sometimes, my shinken or my iaito depending on which one we're talking about.

Why not name your sword Pecker-One and Pecker_Two?

Yes.
My iaito is named "My Iaito". My shinken are named "My Cutting Sword" and "My Regular Sword". Oh, I almost forgot "My Wakizashi" and "My Tanto".

I just KNEW I should have done a poll

I guess I'm a geek then.

My rapier is Fatala, from the Latin fatalus, meaning fated or destined (not fatal, but that gets the same response).

My big knife, I call Shiney. It's shiney.

I suspect that many or most iaidoka don't bother, especially after they've gotten some experience. But when I was considering my first iaito, I admit to having a geeky moment to make that iaito special to me.

I named mine 'tate-ita ni mizu', a four-character idiom in Japanese which literally means 'to flow like water down a post'. It refers to someone babbling (just as I probably am in this post) or speaking quickly. I intended it to refer more positively to 'gaining fluidity' as I wanted to gain confidence and fluidity in both Japanese sword skill, iaido, and Japanese language skill, nihongo.

So the sword itself is a blue-summer-beach theme, with crabs and sea birds, and a waving water texture on the black saya lacquer. I used some black obi silk with a wave motif to make a sword bag for it.

I have no idea if I would name a second iaito. I would probably still put as much thought into a unifying theme and attractiveness, though. It's a practice tool, but it's also a memento that represents my journey.

Hello Halley. Haven't seen you on in awhile. Welcome back. Sorry to hear about Davis-sensei. I don't know if you ever had a chance to train under him, but if you didn't, you really missed out.

BTW. The dates for the 7th US Iaido Embukai have been posted on the MJER forums.
