Thanks for the warm welcome!
Just went through melee.json and tools.json and the only things dealing more than 3 cutting damage with no attack type tags are some unpowered power tools, some traps, blade, circular sawblade, hoe, scythe, sickle, lajatang, glass shiv, crude and forged swords and hunting knife (this one definitely a mistake). Blade and sawblade are pretty obvious, glass shiv also lacks a proper handle, sickle, scythe and lajatang are probably tagless because they’re awkward to use as mentioned in their descriptions. The swords (and also the hoe, to a lesser extent) are a little bit out of the picture here, considering that even the trowel has a [CHOP] tag.
Also spotted that all other fake weapons have [BASH] tags, while nodachi has [SLICE], probably also a mistake.
