I made them myself, they work well. Sized to remove the fasteners that hold together Leatherman PST's, Mini's, and even Rebars............anything that uses the flat-type knurled fasteners of a similar size will fit these.
Note: I found whilst making these, that the manufacturing tolerances on the Leatherman fasteners themselves varies a little from tool to tool. Life isn't perfect

Anyway, your Leatherman may be a hair different to mine, just saying. Fit might be a smidge tighter or looser. (I found that if the socket is slightly loose, you can tighten it by putting the socket on the back of a bench vise, hitting it firmly with a 2lb hammer, and driving the fastener back into it to re-cut the splines).
If the sockets are a smidge too tight, just drive them over *your* PST, using the method I outline at the end of this post.
I made myself Engineers Pliers, so I am offering these up as a giveaway, USA only, shipping free by me.
To win these:
1...USA only.
2...have 100 posts or more.
3...post a brief (or long !!) story, or link to one, telling us how a Leatherman tool "Saved your Day (or someone else's)"
4...pick a number between 1 and 100. I will use a random # chooser the first day of June 2015, and ask for your address if you win.
Note: I am also giving away a pair of Engineers Pliers that I made (PST fastener size). If you want to win those, check this Leatherman forum too. Just one proviso: to spread things around, the winner of the pliers cannot be the winner of the sockets also. Fair??
Have at it

Note: If you want to make a pair of your own, it's pretty easy. I went to the local Dollar Store and got 2 $1 screwdriver sets, the type that have a small selection of sockets inside their handles. The sockets are cheap nasty things, but are made of fairly soft steel, perfect for the application. Drill the 1/4" sockets out just a short distance using a 7/32" drill, force the socket over the PST fastener using a bench vice and flat wooden strips to protect the PST. Done!! No damage to the PST or it's fasteners occurs, assuming you use a bench vice to ensure parallel forces being applied.
After making them, just put the sockets on the screwdriver sets you bought, and mod away. Easier than using a pair of 1/4" socket drivers.
