Black & Decker under counter mounted can opener. Manual can openers are one of the two kitchen items I tend to have self destruct on a regular basis (the other is the toaster, commonly referred to as the “random carbonizer.”

Interesting, because when we bought this house it came with an electric can opener mounted under one of the cabinets. I have NEVER used it, not even once. It just never occurs to me to do so. The manual can opener we have is ancient and I use it all the time (and I’m left handed, to boot, I guess I’ve just dealt with it for so long I don’t think about it). Occasionally I’ll ask the husband to take down the electric one, because it’s ugly and we don’t use it, and he agrees, but then we both forget about it for another year!

Of course, I protested. “My apartment will fit inside that toaster oven,” I moaned. But they left it with me. I set it up, just to see what it looked like and whether it would fit on my countertop. And then…once I used it…it completely replaced my oven. I never use the oven anymore, and there’s nothing this baby can’t do. It does everything. To quote Tom Waits, it can forge your signature and quit smoking.

Love this Tom Waits song - and I love my toaster oven too. It’s a Farberware that toasts, broils, is a convection oven AND is a bread maker. The company does not make them anymore. When it dies, I will cry. I especially like using it in the summer, since it does not heat up the house like the full-size oven does.

Putty knives make great cake frosters.

I have a cookie sheet made of Pyrex. They don’t make those any more either. I loved mine so much that I tried to find another. I’ve never had any luck doing so. They aren’t even on Ebay! I use it for a lot more things than just baking cookies.

Good knives.
[/QUOTE]
Oh yes, cannot underestimate the importance of good knives. But my favorite set is not the expensive Henckels set I got from my parents after I got married. It is the set I got for free for being a regular shopper at our local Harris Teeter. I just love them - the balance and the handles I like a lot better than the Henckels. And when I first took both sets to be sharpened, the place I go to for that told me that they were very impressed with the HT knives; said they sharpened up real well, better than the Henckels. Tis true.
