So that said they probably could use a standard weapon.

Two thoughts on this:

1. A staff like a bishops staff with a Fo1 symbol atop that doubles as a electric sword. It invokes a certain Imperial Guard feel. I feel like an inquisitor should have more of a kick your butt and take names latter so the staff sized electric sword could be reserved for higher level officials/ sort of a staff of office maybe within the Fo1.

2. Gyrojet pistol. Previously its been discussed of gyrojet technology that perhaps it saw distinct development among the yazirians whereas in real world the tech was dropped and one might presume something similar amoung game setting humans. 

The standard side arm of an inquisitor would be a Fo1 issued gyrojet pistol complete with Fo1 crest/symbol on the handle.

The only purpose for the Fo1 crest on the pistol is a bit of foreshadowing- NPC has one so players should be on notice he's supposed to be tough. 

First despite what Star Trek Klingons would have us believe Honor weapons are only used by the warrior class of a race. Even at extremes this would be less than 5% of the total male population. More typically around 1%. Even among that class only the elites would have handed down Honor weapons. Most of the "troops" would not be from warrior class families. The Kurki (knife used by the Gurkhas) is an exception in that it is a utility knife used for tasks other than combat much like the ulu used by the Inuit which is not used for combat.

Second What's with all the metal? A race of tree gliders would have wood as a basis for weapons not all metal throwing disks or swords. I suggest a mostly wooden weapon that could be thrown for hunting or combat and used in melee combat or honor duels depending on the situation would be something close to the ilkwa or the iwisa.

Ilkwa is the Zulu stabbing spear. While not meant to be thrown it could be.

Iwisa is a club used by the Zulu made entirely of hardwood. Again not meant to be thrown but the Yazirian version would be.

Third Forget Gyrojet weapons. Reason kickback. Yazirians are the lightest race and the only ones who fire while in the air. Any weapon with a kickback will effect Yazirians more than the other races. You might say gyrojets have limited kickback since the rocket ignites after leaving the weapon but it still has kickback from the round leaving the barrel. Now laser weapons have no kickback. They are also less bulky and therefore easier for a gliding race to use.

And somewhere along the way, before their space age the likely developed some firearm long before beam weapons. So bullets or gyro-jets. The kickback isnt really an issue: they dont spend that much time gliding as appised to walking aroung. They'll clearly refrain from shooting during gliding although the canon article with the zamra states they duel with the zamra while gliding which seems more problematic to me but its canon so i dont make an issue. 

A modern Fo1 bad arse Inquisitor is probably going to need a modern weapon. He's in peopkes faces so its likely a pistol. It could be any off the equipment list i figure match it to something else that has been linked to yazirians hence the gyro-jet pistols. 

Im not against any of the primitive weapons you suggested. In fact a wooden zamra that presaged the metal one makes sense especially since the article about the zamra mentioned practice zamras if im remembering correctly. 

Wood vs Metal some thoughts.

Metal weapons would be easier to mass produce (heck super hard plastic like kelvar would be easier) and could be made like Honor weapons but this does not mean they are truly Honor wepaons. Katanas were mass produced for Japanese Imperial Army Officers before and during WWII. They were given the honor of carrying them into battle but do not meet the definition presented of handed down honor weapons.

Using Katanas again you can find them for $20 US. These are not honor weapons. The material and craftmanship is not there. To be a true honor weapon that a family would want to hand down it should be made of the original materials by a master craftsman. Modern knockoffs would only be scoffed at.

Of course this does not mean more modern weapons cannot be honor weapons. The Colt M1911A1. You instantly recognized it in your mind. The design is over 100 years old and is still amazinlgly popular. I would consider handed down originals to be an honor weapons. Laser pistols of a particular make with a distinctive history would make the cut. Oh you could say the same for the Colt .45 six shooter, the 9mm Luger, the M1 Garrand, the Brown Bess musket, the Cutlass, the Gladius or maybe something bigger like the M1 Sherman, the Egyptian War Chariot and the Trebuchet.
