It will help if you post the pictures directly on the forum.

Here are two links that will help if you have questions on posting pictures.

Please don't use picture hosting from other picture hosting sites for the forum

You will get more help than by just posting a link. I for one tend not to click on links of unknown origins.

You should also create a brand new thread (and reference the discussion made here).

If you get us a clear focus photo of that kanji and post it in a new thread of your own it will probably be translated for you within 24 hours.

Regarding the "blood groove" -- Stu correctly states that the groove is to help balance the blade. The double concave acts as an "I" beam -- allows flexibility [warp/bend then return to true] as well as lightens the blade.

Grooved blade cross-section:
