I like the PST, and have several. They are light weight for easy pocket carry or belt carry, but the sharp edges are hard on the hands when using the pliers. After getting used to the PST, you will think you have gone to Heaven if you use a Blast or Supertool 300, or one of the other MTs that has a more rounded or ergonomic profile that is easier on the hand. But it is fun to collect PSTs, especially users and beaters, because you can get them at a decent price and then have the fun of cleaning and bringing them back to life. And then there is the black oxide PST, and a relatively rare Japanese version, and the PST II, and . . . .
The PSTs are in the lower left, and a black oxide version is in the sheath at the top left. Just saying.
