Query: A Marvelous Aid

My Salad Shooter (I cheated) is from a yard sale, so it only cost a couple of dollars. But that's because I didn't know that Amazon has them for sale. It is a marvel to use, especially for carrots, hard(er) cheeses, and other firm stuff.BUT -- big warning from experience -- things like bamboo shoots and celery, that have strings in them, just tend to jam it up, so all you do is clean food-jams out (similar to log jams).Either get the strings out (celery) or chop them by hand.Also I think there may be a small problem (after bamboo) with the cutting edges getting dull. Being on the outside of the attachment, it should be possible to sharpen them with a fine file or sharpening stone, or else haunt the yard sales to get replacement parts from people who didn't like theirs...A definite must-have, from somebody who has a KitchenAid Stand Mixer with all the good attachments, and still uses the Salad Shooter for shredding carrots and such stuff. Nice.
