What's the difference between these two models ?

The one I EDC for many years, has the following markings :
LEATHERMAN TOOL
US REG TM 1325473
Portland OR

It consists of : rule, plain blade, file, can opener, philips screwdriver, small, medium and large flat screwdrivers, awl (?) and long roundnose pliers

Is it a PST or a PST II ?
(just curious ... I don't intend to replace it. The pliers and screwdrivers are perfect for my needs)

TIA.

Sounds like an original PST.

The only real difference between the PST and PST II is the the II version sported a pair of sissors. If you don't have the sissors then it's a PST.

no scissors, so it' a PST.

Thanks.
