For the game "Faded Haven" by Pheonix Dream Entertainment.
I did a bunch of different styles simply because, well, there are a LOT of different kind of daggers, and instead of pick one potential theme I went with a few! (and this is for plain-bladed types)!
From the top:
A semi-fine wooden-handle dagger with a gold/brass hilt
An 'infernal' style coiling-pattern ritualistic dagger
A plain black fighters' dagger (same design as the top one- but looked good in two possible configurations).
A 'poor mans' dagger (simple cheap metalworking, with plain leather-wrapped handle
A rich-man's dagger with fine gold, and a handle made of polished bone.
