Besides cooking, my other hobby is woodworking. Many years ago, I happened upon a woodworking rasp called a Microplane. It was (and still is) a fantastic tool. Invented by a man named Richard Grace, the tool is made from a very hard stainless steel that is chemically etched. The result is a long-lasting, razor-sharp, rust-resistant cutting surface that produces shavings, not dust. After gaining accdeptance from woodworkers, somebody got the bright idea that the technology could be put to good use in the kitchen. Today, Microplane's culinary tool business is considerably larger than its woodworking tool business.
Starting with one simple grater, Microplane's range of kitchen tools includes several graters, slicers and shavers. I encourage you to take a look at these tools. I've still got my first Microplane woodworking rasp. After 20 years, it is as sharp as the day I bought it. Since food is a lot softer than wood, I'd put these tools in the lifetime category; i.e., you can leave them to your kids. You can see the full range of tools at us.microplane.com. You can buy them direct, or find them at a discount at places like Amazon. On the website, there is an outlet store with great prices on close-outs.
I am particularly enamored of their new slicing tool which will slice things like potatoes at different thicknesses and will also julienne veggies. A lot more convenient than either a mandoline or V-slicer and takes up very little room in your chachke drawer. Check it out.
