Overview
Leatherman's 831426 folds down to about 3.8 by 1 by 2 inches and weighs 6.88 ounces, with 14 tools built into the one unit. Despite the Knife category label, the piece count points to a multi tool with an integrated blade rather than a single knife.
Leatherman is known for multi tools that combine a knife blade with pliers, screwdrivers and other implements in one folding body, and the 14 piece count here fits that pattern rather than a standalone knife. The compact closed size, under 4 inches long, is built to sit in a pocket or a belt sheath.

Who it's for
Works for anyone who wants one compact tool that covers a knife blade plus other basic functions, rather than carrying a separate knife and toolkit. Anyone who specifically wants a single dedicated blade with no attachments should look at a plain folding knife instead.
Strengths and trade-offs
Drawn from this product's published specifications.
- 14 tools in one compact folding body
- Light at 6.88 ounces for everyday carry
- Small closed size for pocket or sheath carry
- Individual tools on a multi tool are typically smaller than dedicated versions
- Listing does not detail which 14 tools are included
Performance notes
At 6.88 ounces and roughly 3.8 inches closed, the tool is light enough for everyday carry while still packing 14 separate functions into one folding body, which is the main trade off multi tools make against a dedicated single blade knife.
