Inexpensive electric knives - which are just fine for cutting bread - aren't expensive. You can easily buy one for about $20. But then I noticed something: Local thrift stores were inundated with electric knives! Most were in terrific condition, looking as if they'd been used only a handful of times (probably at Thanksgiving and Christmas for a couple of years). Best of all, they were only $2 - $3 a piece! (Most thrift stores also allow you to return electronic items if they don't work the way they should...so you don't even have to worry about loosing $3.)
So yes, I can now confirm that using an electric knife to cut homemade bread is easier - and it makes the bread far less crumbly to eat. And if you browse the thrift stores to buy your electric knife, you'll save a bundle, too!
