Mrhhh. I can see where you’re going with this, but the reason this would probably be frowned upon is because some players like me like to play in the style of not going into towns whatsoever or turning spawn rates super low.
Hence why a sewing kit is kind of inaccessible to these players.
However a bone needle or a wooden needle allows the player to get sewing without breaking their backs on a quest for the sewing kit, and making them downright bad by removing their charge capacity would add limitations to a to a tool that actually makes sense, and to remove the charge capacity even by 1 would remove the ability to craft a shelter kit. And shelter kits are a pretty damn good item in my opinion, as you can make them purely off what the wild offers you.
However I do agree that the overall quality of the tool should be lowered, such as the repair chance and damage chance and blah, then crafting your own little sewing kit from a few rags needles and other things would give you a better tool to allow for some form of tailoring progression.
But blah, needles are an easily accessible tool and a crucial tool for a tailor is they can’t get their hands on a sewing kit, so it might tick off some people if we hardly nerfed the needles.
As for butterfly sutures, that might be a good idea later on in the game, as they may add ‘cut torso’ as a status debuff which you may have to see up again at the cost of pain and thread, but cata isn’t into a stage of detailed body injuries yet.
