Very nice sword, I've been admiring the pictures over the last couple days. I just wanted to quickly jump in to say, leave the tip as is!
I usually go through a process with almost every new purchase where I find something "wrong" and obsess about it for a few weeks. Then I stop noticing it over time.
I think trying to "fix" antiques is a slippery slope and re profiling the tip will just lead to the lose of material and disturbing a rather well developed patina.
Looks great to me as it is.
