Does anyone know how to bring back weapons from previous starbound versions?

I really miss the splatterknife and gutterknife, I remember loving those as a kid and I'd really want to use them again. Unfortunately they were removed from the game ages ago. Any clues on how I could bring them back? Some mods bring back old weapons but so far I haven't found any that bring back those two specifically which are the only ones I'm interested in. Any input is appreciated really
