Hand Tools: Precision pencil compass
Scott Gibson, Contributing Editor
Generals compass is one of the best tool bargains around -simple, inexpensive and reliable. Its spring-loaded arms adjust up to 4 in. apart, enough to scribe new work to even the most crooked ceiling or floor, and enough to draw a 8-in. diameter circle.
Metal construction resists corrosion. Widely available online or from hardware stores, it sold for about $6 in September 2004.
