Ohma blunt sound unchanged when equipping blade skin

[HeartPurity]

Hello, the melee weapon ohma is good but I dislike its low impact weird blunt baseball bat sound, so I plan to buy the tonfa tennoskin with sharp blade but I find out on feedback section that no matter what skin you equip on it, the blunt sound follows. This is weird. I highly suggest sharp blade skin comes with its own sound so that it makes sense, with that blade skin on, ohma is even weirder now, looks sharp but got that baseball bat sound. Pls fix it. Thanks!
