Ultralight Gadgets

Types of knives

• Pocket: Space-saving when the blade is not in use; ideal for hiking, backpacking or everyday tasks
• Fixed-blade: Stronger, heftier and more comfortable in hand; weighs more and requires a sheath for safe carry
• Keychain: Can be carried anywhere, but lacks the strength of larger options

Key features

• Locking blade: The blade folds down for protected carrying, but locks into place when opened to prevent accidental closure when using
• One-handed opening: The folding mechanism makes it easy to push the knife open with your thumb

Choosing a multi-tool 

• Most include essentials like blades, screwdrivers, scissors and bottle openers
• Some have activity-specific gadgets
• May include one or more blades

• Choose a smaller one for backpacking; larger ones work for car camping

What do the numbers mean?

Model numbers on binoculars show magnification and size (objective lens diameter). In 8x42 binoculars, the 8 is magnification, and 42 is the objective lenses.

Choose your magnification

• 8x: Wider field of view
• 10x: Closer, more detailed look

Size

Size is based on the objective lenses (the second number)

• Compact: Under 30mm (8x25, 10x28); lighter weight
• Midsize: 30mm-40mm (10x30, 8x32)
• Full-size: Over 40mm (8x42, 10x50); brighter image but heavier

Best for your activity

Wildlife viewing

• 10x if watching animals from a distance
• Midsize if you want something more compact

Birding 

• Midsize or full-size models if weight isn't a concern
• 8x for a wider field of view to locate birds

Hiking or backpacking

• 8x or 10x magnification
