Query: Best knife ever

Klein Tools 44032 pocket knife...I have carried mine daily for over twenty years. Although I use it mostly for the occasional box and letter opening, it has performed flawlessly since new. It not only looks good, it has held up well and has kept its edge, even after passing through the washing machine many, many times. An occasional sharpening and oiling is all it needs to perform for life. I am so impressed with performance that I have purchased one for each of my three sons. If you want a rugged knife that will last a lifetime, you will not be disappointed in choosing this one!
