The SOG Powerlock has been out for quite a while and has remained the company's flagship. SOG is a company that is slow to make changes in their tool line. They feel that what they make is darn good and they make changes to their products when they feel the time is right. SOG took a second look at their very popular Powerlock model, made a list of all the pros and cons they have noticed over the years and decided to give this old gal a facelift. Some of the things that SOG focused on with this remodel were the gears that drive the compound leverage of the pliers, new locking system for the tools and the ability to keep their tools from clumping when finding the tool you need.
The first thing you notice when handling the Powerlock 2.0 is the new plier head. SOG worked on a collaboration effort with Paladin tools to create a multitool line for the telecom industry. Those tools became a testing ground for what would become the new Powerlock design.

Similar to it's more affordable cousins, the standard Skeletool and the yet to be released Freestyle, the Skeletool CX is the premium model in this particular line. It boasts the same features as the standard model, but with a few extra bonuses.

If ever there was the One Tool to Rule Them All, it’s Leatherman’s Pocket (or Personal) Survival Tool, affectionately known as the PST. This was the original Leatherman production model, and the source of inspiration for all current issue multitools, and the One Tool (see?) that was single handedly responsible for resurrecting a virtually extinct niche market and bringing it to the masses.

Another member of Leatherman’s Charge family, the Ti is now discontinued, along with it’s original titanium handled sibling, the XTi . While the XTi was replaced by the ALX model, the Ti was replaced by both the AL and TTi models.

Early last year the tool world was all abuzz about the new Guppie multitool from CRKT. It was based on a wrench platform and had a form factor like no other device that comes to mind. In 2008 the Guppie gave birth to an offspring that was designed to be precisely 50% lighter than the original. Fittingly called the Li’l Guppie, this new gadget from CRKT seems to be targeted at the keychain tool niche currently occupied by such tools as the Leatherman Micra, SeberTool M4 and SOG CrossGrip.
