Some of the most famous regiments in the galaxy are known for their distinctive gear. A Catachan would sooner lose his hand than his knife. The lasgun that a Vostroyan wields is a symbol of his lineage extending back into history. The Death Korps of Krieg utilize powerful modified lasguns in combat.
Has anyone taken a swing at these distinctive weapons?
Catachan Knives come in three varieties: the Catachan Fang is probably most easily written out as a Best-craftsmanship Knife, while a Night Reaper (used for nighttime ambushes) would likely have Tearing and Toxic (1), and the massive Devil's Fang would be a Mono-sword with Tearing and/or Razor-Sharp.
The Death Korps do not use the common M36 Lasgun, instead trusting in the slower but more powerful Lucius-pattern. The Lucius fires more slowly (perhaps lower the RoF to S/2/- or even S/-/-) but hits harder. I'm torn between 1d10+4 Pen 1 or 1d10+5 Pen 0.
The Tallarn Desert Raiders utilize the long-barelled Mars-pattern Lasgun. I feel like it is represented just fine by a Long-las.
The Elysian Drop Troops have standard Lascarbines.
I feel like the age of a Vostroyan Lasgun is best represented with two Weapon Customizations on it.
