Hello,
Ancestral weapon reads:

You blend monastic techniques with the ancestral fighting styles of your people. Choose an ancestry for which you have access to all weapons with that trait. For you, melee weapons with that ancestry trait and either the agile or finesse trait gain the monk trait.

I am trying to figure out which races have superb racial weapons that would work well for the ancestral weapon feat the monk can get at level 2.

I was thinking about trying to go with the catfolk because a clawed monk should wreck the home imo from a flavour perspective, however I haven't played yet and it looks like weapons can be a huge part of the overall game since so many weapons have exciting abilities almost attached to them.

Objectively, it looks like the Bo staff is just better:

Price 2 sp; Damage 1d8 B; Bulk 2
Hands 2
Category Martial
Group Club; Traits Monk, Parry, Reach, Trip

However, I was thinking about the Claw Blade

Price 2 gp; Damage 1d4 S; Bulk L
Hands 1
Category Martial
Group Knife; Traits Agile, Catfolk, Deadly d8, Disarm, Finesse, Uncommon, Versatile P

Am I missing something here. Looking at the Bo staff for combat I could trip then flurry of blows and then parry. All of which seems awesome, it also has a larger damage dice.

On the other can, the Claw Blade seems weaker overall with a 1d4? I am not sure how useful disarm is and since I haven't played, yet I don't know how often critical come into play, but overall it seems like even the unarmed strikes are better than the Claw Blade.

So my question is how big of a difference when I am actually playing will the difference in abilities and damage be. It seems like a really large differences, am I missing anything here. I would love to hear your thoughts on what some good Ancestral weapon choices would be.(Since I am investing 2 feats, I really want to find a weapon that is super dope ;) )
