Should I Trade All Of This For Ice Katana!?

I really do want Ice Katana but I’m afraid that I would have to lose all of my weapons just for Ice Katana to flop… My weapons are Loveboard, Sakura Blade, Freeze Gun, Brass Knuckles, & Spiked Purse. I heard rumors that Ice Katana is dropping, but should I trade all of my weapons for Ice Katana!?
