I've been building bug-out bags since my oldest kid was in middle school. Over the years I've stripped out a lot of gear that seemed essential and turned out not to be. The Leatherman Wave+ has never left the bag. Not once. Because when things go sideways in the field, you're almost never missing a knife or a fire source. You're missing the ability to fix something, tighten something, cut something that isn't a straight line, or pry something that's jammed. That's what the Wave+ handles. It's 18 tools in a package that weighs 8.5 oz.
I'm not going to tell you it's cheap. It's not. But it's the only item in my bag that has replaced something different every time I've used it. Here are the 10 reasons I've stopped questioning whether it belongs in there.
If your bug-out bag doesn't have a multi-tool yet, this is the one I'd start with.
The Leatherman Wave+ has 18 tools, a 25-year warranty, and has been in my rotation for four years without a single failure. Check today's price before it changes.

Pliers, wire cutters, two knife blades, saw, file, scissors, multiple screwdrivers, bottle opener, can opener, and a ruler. The Wave+ carries 18 tools that you'd otherwise have to pack individually or leave behind. In a bug-out scenario where every ounce is negotiated, that matters. I've used the needlenose pliers to pull a hook from a fish, the saw to clear a deadfall from a trail, and the flathead to tighten a loose pack frame screw, all in the same weekend.
The Pliers Are the Thing You'll Actually Use Most
I know the knife blades get all the attention. But in four years of daily carry and backcountry use, I've grabbed the pliers on this thing more than any other tool. Twisted wire, bent stakes, tight bolts, stuck zipper pulls, improvised clamps. The Wave+ pliers open from the outside so you can access them one-handed, and the spring-loaded return makes them easy to use with cold hands. In October in the Cascades, that's not a small thing.
Both Blades Are Accessible Without Opening the Tool
This is what separates the Wave+ from a lot of competitors at the same price point. Both the plain-edge and serrated blades deploy from the outside of the closed tool. You don't have to unfold the whole multi-tool to get your knife out. In a real emergency, that one feature is worth the price of admission. I've used the serrated blade to cut webbing, cordage, and the sleeve off a wetsuit that was locked to a friend's ankle after a creek crossing. One-handed, gloves on.
It Can Handle Light Gear Repair in the Field
Snapped tent pole ferrule. Blown zipper pull. Cracked pack buckle. These are the things that turn a manageable situation into a miserable one. The Wave+ file, screwdrivers, and pliers cover most field repairs short of a busted frame weld. I used the flathead on mine to bend a replacement eyelet into shape after my headlamp buckle cracked at 4,000 feet on a November trip in the Olympics. It's not elegant, but it worked, and I made it back to the trailhead dry.
The Scissors Are Legitimately Useful, Not a Gimmick
Most multi-tool scissors are terrible. These aren't. The Wave+ scissors are spring-loaded, open and close smoothly, and can cut moleskin, first-aid tape, thin cordage, and fabric without chewing through the material. In a medical situation where you need to cut clothing away from a wound or trim a bandage to size, having scissors that actually work matters. They're also handy for cutting food packaging when your hands are wet and cold and a knife is overkill.
The Wave+ is the only item in my bag that has replaced something different every single time I've needed it. Four years. Not once left it home.
It's Built in Portland, Oregon and Backed by a 25-Year Warranty
Leatherman has been building tools in Portland since 1983. The Wave+ comes with a 25-year warranty that covers defects in materials and workmanship. I've never had to use it, but knowing it exists takes real-world pressure off my decision to depend on this tool when things get serious. Buy cheap tools for cheap jobs. Bug-out gear isn't a cheap job.
It Clips to Your Belt or Bag Strap and Stays Put
The Wave+ ships with a nylon sheath that fits on a standard 1.5-inch belt, but it also sits flat enough to clip to a molle strap or slip into a pack's outer pocket without creating a bulge that catches on everything. I clip mine to the left shoulder strap of my main pack so I can reach it without dropping the bag. In a scramble situation where I need the tool fast and don't want to dig through 40 liters of gear, that positioning is a real advantage.
The Saw Cuts Green Wood
This is not a chainsaw replacement. It's a 2.9-inch wood-and-bone saw that will cut through green alder or small fir branches in a few minutes of focused work. Enough to build a basic lean-to support pole, clear a branch blocking a campsite, or notch a post for a ridge line anchor. In a shelter-building scenario where you don't have an axe or folding saw, it closes a gap that would otherwise leave you exposed.
8.5 Ounces Is Not a Significant Weight Trade-Off for What You Get
I hear the ultralight argument. I'm not unsympathetic to it. But in a bug-out bag context, weight isn't the only variable. Capability per ounce is. The Wave+ at 8.5 oz gives you more functional capacity than almost anything else you could put in that space. Compare it to carrying a dedicated knife (3-4 oz), scissors (2 oz), a small file (1 oz), and a screwdriver set (4+ oz) separately. You'd be over 10 oz before you matched what the Wave+ covers, and you'd have four things to lose instead of one.
You'll Find Uses for It You Didn't Anticipate
The first time I used the Wave+ to crimp a loose splice on a water filter bag, I hadn't planned for that. The first time I used it to tighten a stripped screw on my headlamp housing in the dark, I hadn't planned for that either. That's the real argument for a multi-tool in a bug-out bag. It covers failure modes you haven't predicted. Your knife will handle most cutting. Your fire-starting kit will handle ignition. But the gap between those two things is where the multi-tool earns its place.
What I'd Skip
If your bag is already over 35 pounds, the Wave+ may not be the right call. It's a quality-of-life and problem-solving tool, not a survival baseline. Water, shelter, fire, and navigation come first. Add the multi-tool when those four are covered. I'd also say skip the cheaper alternatives unless you've handled them in the field. I tried two other multi-tools before settling on the Wave+. Both had lock failures within 18 months of regular use. The Wave+ has none of that in four years of daily carry.
Skip cheaper alternatives if you're depending on this tool in the field. Lock failures on a multi-tool at the wrong moment are a real problem.
Four years of daily carry and it's never failed me once. That's the only endorsement I can honestly give.
The Leatherman Wave+ is rated 4.7 stars across more than 4,400 verified reviews. It's the multi-tool I'd hand someone who is serious about their bug-out kit and isn't willing to compromise on the tool they depend on most.
