Still a great tool that's very capable if you treat it right and have realistic expectations of it.
They got the job done throughout the 80's and most of the 90's, they still can today but people just expect more.
My favorite current model is the bond because it's basically an adaptation of the PST, I'm clearly not one of those people who really expect more in a multitool.
I will say that I find the Bond better than the PST though, and it's not even because of the rolled edges which are appreciated.
The PST awl is basically useless for anything but piercing a new hole into a belt, the current leatherman awl is excellent because it's fairly sharp and pointy.
