Delicato squash

A month or two back I bought a delicato squash at the farmers market along with acorn and butternut squash. I was going to cook one tonight but that didn't go well. 
I have never seen a squash this difficult to cut. I had to baton the knife to get into it and it broke apart by the time I was done. Is it possible to hybridize the dang things with hickory? Maybe they're not good storage squash? 
Anyhoo, there's an acorn squash in the oven now.

Never heard of a delicato squash before

Delicato is close to ornamental only imo. The only squash I really like is the smooth - skin yellow squash.

The guy I bought it from said it's not as sweet as a butternut, but very good. It certainly looks like an ornamental.
