Best Climbing Knife 2021

Carrying a knife while climbing might seem strange, even unsafe. But there are many reasons for having a knife, especially on multi-pitch or alpine routes. Some common uses include cutting old webbing from existing rappel stations, cutting new webbing for rappel stations, first aid, cutting a stuck or damaged section of rope, or even just for cutting meat and cheese for lunch. While many of these scenarios might not happen very often, when you need it, it’s critically important. For this reason, pretty much every professional climbing guide considers a knife an indispensable part of their climbing kit. There are lots of options out there for climbing knives. Here’s our list of the top climbing knife options on the market, sorted by category, to help you find the very best climbing knife for you.

Bargain Hunter’s Favorite

Razorblade

Price: ~$1

Weight: ~5 grams

Blade Length: 1.5 inches

Maybe the best climbing knife isn’t a knife at all, but a razorblade. Create your own climbing tape pouch (make sure its thick and holds the razorblade snugly) and store it in your chalk bag, climbing pack, or even in your helmet.
Super cheap and lightweight it’s a no brainer for those on the fence about even carrying a knife.
Easy to set up and forget about until you really need something that can cut.
