The 8.2-ounce Leatherman Charge TTi features titanium handles, a knife blade made of S30V stainless steel, a wire crimper and -- especially useful -- a V-cutter at the end of one of the blades. Its four blades open one-handed, without the user having to open the handles: They are the basic knife, a serrated knife with the cutting hook, a saw and a diamond-coated file. A ruler runs along the edge of a handle, and both a pocket clip and lanyard ring come with the Charge TTi.
Opening the handles produces the pliers (which combine needlenose and regular pliers), along with wire cutters, hard-wire cutters and a wire stripper and crimper. The handles include additional tools: scissors, bottle/can opener, large screwdriver and two bit drivers (small and large). Eight driver bits are included, and a 40-piece bit kit is also available (*Est. $12). The bit drivers fold inside so the bits can't drop out while carrying the Charge TTi. Weight is the big drawback. Experts say that for a lighter "carry-everywhere" multitool, you might consider the Leatherman Skeletool CX (*Est. $65).

1. Outside Magazine
The Leatherman Charge TTi is included in a buyer's guide to top gear for the outdoorsman here. Though extremely short, the write up is provided by an experienced reviewer for Outside magazine. He recommends the Leatherman Charge TTi for its "titanium handles and a veritable panoply of smart, multifunctional utensils."

2. Multi-Tool Museum
Two earlier but similar models of the Leatherman Charge are covered here. They share top ranking with the Victorinox Swiss Tool X as the best all-around multi-tools -- with tools that are easy to access yet lock well into place. A few minor drawbacks are noted; for example, the scissors are small.
Review: Top Multi-Tools, Editors of Multi-Tool Museum
About 60 owners give the Leatherman Charge TTi mostly high praise for its locking tools, easily accessible blades and the high-quality steel used on the knife. A few report quality-control issues, including trouble opening or closing one or more of the tools.

More than a dozen owners review the Leatherman Charge TTi here, with high praise for its comfort and quality. Despite its price and weight, these owners say it's the best choice by far.
This is the first of two 10-minute-plus videos comparing the Leatherman Charge TTi with a similar model, the Leatherman Wave. The second video compares the cutting ability of the TTi and Wave, with the former getting the edge in both comfort and cutting performance.

This 7-minute video quietly demonstrates the Leatherman Charge TTi in action, showing how all the tools lock open and perform. For example, the author opens a can, peels an apple and -- with the cutting hook, slices open a cardboard box.
