Today, I carried the Tangram Santa Fe. That delightfully thin blade sailed through a few envelopes and opened a few packages. It cut a few boxes down to size. It trimmed a loose thread from a sock. It liberated my peanut butter crackers from their plastic sleeve. It stabbed a large beetle that had found its way into my car and helped me to fling it out the window. Then it waited patiently until I could wipe it off with an alcohol swab.
