KS3870: 3870 Amplitude 2.5
Kershaw Knives

Kershaw and Todd Rexford have teamed up to bring you a smaller pocketknife with plenty of style: the Amplitude 2.5. As you might guess, the Amplitude 2.5 features a 2.5-inch blade. When closed, the knife is a compact 3.5 inches long.

The Amplitude 2.5’s blade is heat treated to Kershaw’s demanding specifications to bring out the very best qualities in the steel. A machine satin finish on the blade and cool, grey titanium carbo-nitride coating on the steel handle give the Amplitude 2.5 a sophisticated look. For easy carry, a left/right reversible pocketclip is included.

This no-nonsense smaller knife offers simple, clean lines, a drop-point blade, and a smooth all-steel handle. So that the Amplitude 2.5 is ready when needed, it can be opened one-handed thanks to SpeedSafe® assisted opening accessed with the handy, built-in flipper.

Easy to carry in pocket, briefcase, or backpack, the Amplitude packs a lot of style into a smaller package.
  • Flipper - May be used on either manual or assisted opening knives. The “flipper” is a protrusion on the back of the blade that the user can pull back on, or flip, in order to move the blade easily out of the handle.
  • SpeedSafe® - Assists you to open any SpeedSafe® knife quickly and easily with a manual push on the thumbstud or pull back on the flipper; built into many Kershaw best sellers.
  • Frame Lock - A portion of the handle (the knife frame) moves behind the blade to lock it into position during use. This is a safety feature of the knife.
  • Reversible - Pre-drilled holes in the handle enable the user to change either the tip position or the side on which the knife carries.

Pros: Lock Ease of Use, Ease of Opening, Overall Quality
Cons: None
My Idea of a Good Every Day Carry/Use Pocket Knife
Well designed EDC pocket knife. Solid, nice size, useful blade shape, good choice of materials, good workmanship, snappy action, solid lock-up ... moderately easy to do maintenance when/if needed ... perhaps a bit heavy for some tastes, I'm okay with it.
