Sometimes a normal-sized tool is just too big for small spaces. For those occasions, the Tight Spaces tube cutter can help. The cast aluminum and stainless steel product features a compact design, so it will cut rigid copper in tight or cramped spaces. It requires only ½-inch clearance to make a cut, and its brightly colored arrows show which direction to turn it. Cost: $7.99 to $19.95. Lenox. 800-628-3030.
