Light weight, fits in pocket easily. Markings are in 32nds, and 64ths--good for very fine work.
Cons? Kind of easy to misplace due to its size. Not suggested for heavy work--the flexibility is great, but don't repeatedly bend it too much.
Thank you, Sir. I've had a C334 in my arsenal since 1982 when I graduated from the Naval Academy. A cherished tool I got just a bit too close to 220v feed and burned the ends a bit. Nice to have fully functional ones again to get me through the next 42 years....
