I know that the bottom character is mitsu but everytime I check the first one it doesn't match Kane for what I can find... I understand that this might read Kanemitsu? Would I be correct, there were so many sword smiths by the name Kanemitsu it's hard to even figure out which one it might be.

It's Kanemitsu. 

There are a surprising number of variants for the kanji 兼

I had this from Hawley’s “Japanese Swordsmiths Vol 1 & 2” but Steve’s answer is more informative.
