I have really become a SOG powerlock fanboy. I used to be a very big Leatherman afficienado, and I still like the company and the original PST design- it was slim, well made, and very functional.
At 10 years old (to the month I believe, if not it was pretty close or just over a pivot went. Leatherman did replace it with a Leatherman Blast- $50 to $60 tool. The blast is nice too, but like most Leatherman products, it has the same pivot system and will eventually wear and fail the same way- especially under hard use. It's not a matter of if, but when (of course, that when will likely be 10 or more years down the road).
The Sog Powerlock however is a beast. Like a tank, it's heavy, and you could probably pound on it all day without breaking it- it's the like the Chuck Norris of multi tools. The gear pivot takes up a lot pressure and the one hand plier opening is wicked cool and handy. The Sog also is more corrosion resistant than my Leatherman- the Leatherman developed some oxidation in the individual tool joints.
The Sog is definetely a sheath carry item. The PST could carry easily in a Carhart pocket. The sheath Sog gives you makes Leatherman current production leather sheathes look like and inferior joke.
I did find the locks on my blast just a little more solid than the Sog. However, the Sog's broke in nicely.
The other nice feature about the Sog is that the user can chamge out the tools rather than shipping the knife back for warranty. This also allows a degree of individualization with risking tool damage.
