Sawblade Ballista
actually shoots arrows because only arrows are allowed to have the penetrate attribute and you can't change their model, atleast for now
there is no server where you can play with this, but you can now download the pack yourself and test it on offline server: https://gamebanana.com/mods/481173 (will update this month, promise.)
Also keep in mind these weapons are proof of concept, so if you have a suggestion for a change tell me in the comments
made this on local server with bots
