Leatherman strips the multi-tool down to the tools that actually get used and does them brilliantly. Pliers, a partially serrated knife blade, a bit driver that works with standard bits, and a carabiner clip for belt or bag carry — all in 142 grams that you genuinely won't notice in your pocket. The quality is Leatherman throughout: the pliers open smoothly, the blade is properly hardened, and the whole thing will outlast most other purchases you'll make this year.
The multi-tool by which all others are judged — 18 tools including outside-accessible blades so you don't have to open the pliers to use a knife, 154CM steel that's properly hardened, and Leatherman's 25-year warranty that they actually honour. The Wave+ is the tool that outdoor professionals, tradespeople, and serious hobbyists all eventually settle on after trying alternatives. If you buy one multi-tool in your life, this is the rational choice.
The Signal adds genuine survival tools to the Wave platform — a ferro rod fire starter that works even wet, an emergency whistle rated to 100 decibels, and a safety cutter for seatbelts and rope. Nineteen tools total, a glass breaker for vehicle emergencies, and the same 154CM steel and 25-year warranty as the standard Wave. Designed for situations where every tool in your pocket earns its gram. The multi-tool for people who actually go places where things can go wrong.
