It would soften it enough to make cutting it much easier.

I use a big meat cleaver when I slice squash in half.

Like a baked potato to soften it up.

It can also be cooked whole.

in a crock pot with some water for an hour or so.

I had trouble cutting up sweet potatoes to make oven fries. I microwaved them until they softened enough to cut. It didn't seem to change the finished fries much.

And it's a godsend for large things that need to be cut- I use it on squash, on large grapefruit and pomelos, on jicama and a whole lot of other big things that need to be cut into pieces before I work on the pieces with a paring knife, peeler, etc.

I believe you can also get non-serrated versions.

I originally got mine at IKEA which no longer sells them, but you can find something similar at Amazon:

I have always had a hard time w/ the large fruits and veg when I was cooking for more than 2.

But cooking for 2, I find I just buy the smallest stuff I can get.

That kitchen saw looked pretty good too.

the week, it's just for 2.

Thanks for everyone who replied. A friend of mine suggested that I ask the people at the grocery store to cut it for me before I leave the store. She said she does that all the time. I think that's the easiest and cheapest solution.
