I can't imagine a huge hubbard squash. I recently had my Henckel's knife sharpened....so that I could cut into butternut squash. I cut it up to cook it (I stir fry it. It is delicious. No need to use sugar/sweetening agent at all.) and freeze bags of raw pieces for winter months. It's effort and requires rocking the knife slowly through the squash ..to cut it all the way through.
