Yotsuba, for better or worse, wasn't an expert on knives, so she couldn't really say how terrible or not the knife was. She hadn't been trained in normal fighting-just how to use a sling-but she wasn't going to mention that, thinking that she had the basics of fighting pretty much covered.

"Okay! Yotsuba can use it! But you don't hit people! You stab them!" Yotsuba happily chirped as she took the pretend knife and copied Romeo's defensive stance as best she could.
