what axe is suitable?

I'm going to disagree with some people in this thread about starting and getting a relic weapon. At this stage of the game, your best bet would be to save up some money (start crafting and sell low level crafting items if you have to) enough to buy the 110 wootz axe. Even normal quality would be perfectly fine. This will give you a huge leg up into starting to tank end game.

The relic is done within 5 days at max. Then other 1-2 days to get the tomes to upgrade it to a Zenith.
Faster than starting to save up money.

Even 5 days is not even trying. My friend got to 50 last week and we got him within that evening. We had to buy/make a few minor pieces like jewelry (only even ilvl 55 stuff too), to reach the item level requirements for Titan(HM).
He actually had the needed solidiery for the upgrade from the main scenario quests he did once he reached 50, in addition to the Adampor Keep and the Primals.
We did like one extra dungeon to get the Zenith.

Don't forget if you're new to the instances, you get bonus solidiery which is quite a lot anyway.

Then 90 weapon isn't that high, but it takes nothing to get. Probably 3 hours max.
