In 1998, the Leatherman PST II tool had a screwdriver overhaul. The original L-shaped tools used in 1997 and earlier were replaced by slightly lighter, tapered ones. The change happened gradually, so there are transitional tools with just one L-shaped screwdriver. Late in the year, the label changed from Leatherman Tool to Leatherman PST II, so it finally was easier to tell the two PST models apart. That configuration continued into 1999 and subsequent years.
