In this case it's more that the only things shown to be durable enough to cut mature life-fibers are 1: Other mature life-fibers compressed and hardened into a metallic substances(the rending shears) or whatever the hell unique metal the sword bakuzan was made from.

(All we know about Bakuzan is that it can cut life-fibers, cut metal, but unlike the scissor blades is not indestructible. And that it can be grafted to a human body without any serious issues—Satsuki had her toe-nails replaced with fake ones made of the same metal.)
