Best Knives for Backpacking and Thru-Hiking 2026
When you’re counting grams and every item in your pack has to earn its place, your knife choice becomes a surprisingly important decision. A backpacking knife needs to be light enough to forget you’re carrying it, capable enough to handle trail tasks, and reliable when you’re miles from the nearest road. After testing dozens of ultralight blades across hundreds of trail miles, we’ve identified the five best knives that truly earn their weight on the trail.
What Makes a Great Backpacking Knife?
Backpacking knives live in a different category from your everyday carry or bushcraft blades. The primary constraint is weight — every ounce matters when you’re walking 20+ miles a day. But ultralight doesn’t mean useless. A good backpacking knife still needs to cut food, open packaging, trim moleskin, repair gear, and handle the occasional whittling session at camp. The sweet spot is typically under 3 ounces (85g) with a blade between 2 and 3.5 inches.
Corrosion resistance is another critical factor. You’ll encounter rain, humidity, sweat, and food acids — and you won’t always have the luxury of drying and oiling your blade immediately. Stainless steels dominate this category for good reason.
The 5 Best Backpacking Knives for 2026
1. Benchmade Bugout 535 — The Gold Standard
Weight: 1.85 oz (52g) | Blade: 3.24″ CPM-S30V | Price: ~$180
The Benchmade Bugout didn’t just set the standard for ultralight EDC knives — it redefined what’s possible at under two ounces. The 535 features Benchmade’s legendary AXIS lock mechanism, a drop-point CPM-S30V blade that holds an edge through extended trail use, and Grivory handle scales that keep the weight shockingly low without sacrificing rigidity. The deep-carry pocket clip is reversible for left or right carry, and the blade deploys smoothly with one hand — essential when your other hand is holding a tent pole or trekking pole.
On the Pacific Crest Trail and Appalachian Trail, the Bugout has become the knife of choice for serious thru-hikers. Its 3.24-inch blade is long enough for food prep and gear repair, yet the entire package disappears in your pocket or hip belt. The S30V steel holds an edge remarkably well — you can go weeks between sharpenings even with daily use.
2. Spyderco Dragonfly 2 — Tiny Titan
Weight: 1.2 oz (34g) | Blade: 2.28″ VG-10 | Price: ~$85
Don’t let the diminutive size fool you — the Spyderco Dragonfly 2 punches well above its weight class. At just 1.2 ounces, it’s the lightest knife in this guide, yet the full-flat-ground VG-10 blade slices with authority thanks to Spyderco’s signature leaf-shaped blade profile. The ergonomic FRN (fiberglass reinforced nylon) handle features Bi-Directional Texturing that locks into your grip even with wet or cold hands.
The Dragonfly 2’s secret weapon is the forward finger choil, which lets you choke up on the blade for detailed cutting tasks — think removing splinters, precision gear repair, or trimming first aid supplies. The back lock is rock-solid and the wire clip carries deep and discreet. For ultralight backpackers who count every gram, this is as light as a capable locking folder gets.
3. Victorinox Classic SD — The Multi-Tool Minimalist
Weight: 0.74 oz (21g) | Blade: 1.25″ Stainless | Price: ~$20
The Victorinox Classic SD isn’t just a knife — it’s a 7-function multi-tool that weighs less than a Clif Bar. In addition to the 1.25-inch blade, you get scissors (invaluable for trimming moleskin, cutting Leukotape, or snipping thread), a nail file with screwdriver tip, tweezers, and a toothpick. The scissors alone are worth the carry — they handle first-aid tape and thread better than any knife blade can.
At under $20, the Classic SD is also the most affordable option here. Many thru-hikers carry this as their only cutting tool. It resides on a keychain or clipped to a pack’s sternum strap via a small carabiner. The stainless steel is easy to maintain, and Victorinox’s legendary build quality means it’ll last for thousands of trail miles. If you’re a gram-counting ultralighter who values multi-functionality over blade length, this is your knife.
4. Opinel No.8 — The Classic Ultralight
Weight: 1.6 oz (45g) | Blade: 3.25″ 12C27 Stainless | Price: ~$18
The Opinel No.8 has been gracing backpackers’ pockets since 1890, and for good reason. The beechwood handle is lightweight, warm to the touch, and develops a beautiful patina over time. The 12C27 Sandvik stainless steel blade (on the stainless version — carbon steel is also available for traditionalists) takes a razor edge and is remarkably easy to maintain on the trail.
The Virobloc safety ring locks the blade open or closed — a simple but effective mechanism that’s been refined over 130+ years. At 1.6 ounces, the Opinel is lighter than folding knives costing ten times as much. It excels at food prep at camp — slicing cheese, sausage, and bread with its thin, flat-ground blade geometry. The classic French profile is also non-threatening, which matters when you’re sharing a shelter with other hikers.
Pro tip: Get the stainless version for backpacking. Carbon steel takes a sharper edge but will rust if left wet in your pack. The beechwood handle can swell when wet — a light coat of mineral oil before your trip prevents this.
5. Gerber Ultralight LST — Budget Champion
Weight: 0.6 oz (17g) | Blade: 2.0″ 420HC | Price: ~$15
At just 0.6 ounces, the Gerber Ultralight LST is the lightest locking folder in this guide and possibly the lightest locking knife on the market. The glass-filled nylon handle and 420HC steel blade create an incredibly minimalist package that still features a reliable lock-back mechanism. For ultralight backpackers who want a locking blade but refuse to carry anything over an ounce, this is the answer.
The 2-inch blade is modest but sufficient for most backpacking tasks — opening food packaging, cutting cordage, and light whittling. The 420HC steel won’t hold an edge as long as premium steels, but it’s extremely easy to sharpen (a few passes on a pocket stone or even the bottom of a ceramic mug gets it back to shaving sharp). At this price point, you won’t cry if you lose it on the trail — though many hikers report their LST lasting for decades.

Choosing Your Trail Companion
Your choice ultimately depends on your hiking style and priorities:
- Thru-hikers obsessed with weight: Gerber LST (0.6 oz) or Victorinox Classic SD (0.74 oz with scissors)
- Backpackers who want one capable blade: Benchmade Bugout — light enough for thru-hiking, capable enough for real work
- Budget-conscious hikers: Opinel No.8 or Victorinox Classic SD — both under $20 with legendary quality
- Ultralight with premium materials: Spyderco Dragonfly 2 — the lightest knife with premium VG-10 steel and superb ergonomics
Whatever you choose, remember: the best backpacking knife is the one you’ll actually carry. Every gram saved is a gram you can put toward extra snacks — and on a long trail, that’s a trade worth making.
