Leveling weapons for blade flurry?

Guides only seem to say to use Bino's but umm that requires level 68 so yeah what am I meant to use to level and farm the 100c for Bino's? Any good unique weapon I should grab? I assume they don't expect you to be bare handed :P

Any decent Claw, Dagger, or One-Handed Sword will work. Presumably, daggers would be preferred since the guide gives Bino's as the endgame choice.

You can Trans/Alt/Aug a good dagger yourself. Or check wiki for list of Uniques, if you're more into brown.

If you must follow a guide, any "Beginner Reave Build" or "Budget Reave Build" should have the information you're looking for; Budget/Beginner Lacerate build should work too most of the time (but ignore any Axe or 2-Handed Sword suggestions there).

EDIT: Forgot to mention. Since you're a new player, you probably don't know what I mean by "good dagger."

At the very earliest levels, you just want daggers, claws, or swords with DPS mods. "Adds x-y Z damage." "Increased attack speed." As your level climbs and you allocate more passives, though, you'll start to want to favour Physical modifiers, mainly "x% increased physical damage" of a good size, preferably with "adds x-y physical damage" but it's not necessary. x% attack speed helps there too.

Mightflay is a great dagger for Bladeflurry leveling past level 35 when you can equip it. There are also some good lower level one handed swords that you can use. Otherwise you want a dagger with good attack speed and high physical damage. I wouldn't worry too much about crit at low levels, since you won't have scaled crit high enough to be a big difference. You can get a lot of damage early on running Hatred and Herald of Ash also.
