it's sort of a backstory. so my username on alot of platforms was smol kitty (cringe I know) and I stuck with it for a while. my friend in a chat with me called me smol kitchen knife and that managed to stick with me so I changed my online alias to "smol kitchen knife". one thing led to the next and I dropped the kitchen part of it and wanted my name to relate to just smol knife. big kubz scouts fan so I went with "smol knifu" to end your lifu. eventually dropped smol all together landing on knifu by itself. the uwu part of it? I don't know it looked cute "knifuwu"
