This is a solid automatic knife at a fair price. Press the button, blade deploys — no wrist flicking, no fumbling. The 5-hole handle gives you a secure grip even with wet or sweaty hands, and the safety lock keeps the blade from deploying in your pocket. Stainless steel, 3.5-inch blade, 8 inches overall. It does what it's supposed to do.

  • Automatic spring-assisted deployment — press the button, blade is out
  • 5-hole handle design for improved grip and reduced weight
  • 3.5-inch stainless steel blade with 4.5-inch collapsed length
  • Safety lock prevents accidental opening during pocket carry
  • 8 inches overall — practical size for everyday tasks and carry

A Working Automatic Knife Without the Markup

Here’s the deal — there are automatic knives that cost three times this much and don’t do anything this one can’t do. This is a heavy-duty automatic with a stainless steel blade, a spring-loaded deployment mechanism, and a safety lock. It opens fast, locks solid, and fits in your pocket. That’s what you need from a knife. Everything else is marketing.

Who This Knife Is For

This is for the person who uses a knife as a tool, not a showpiece. You’re opening boxes, cutting cord, breaking down cardboard, handling everyday tasks where a reliable blade makes life easier. You’re a warehouse worker, a handyman, someone who works with their hands. You want one-handed opening because your other hand is busy. The automatic deployment gives you that without any wrist-flick technique to learn.

Is This the Right Choice for You?

Choose this automatic knife if you want:

  • Fast, reliable one-handed blade deployment
  • A grip-friendly handle that works with wet or gloved hands
  • A practical everyday knife at a reasonable price

Consider something else if you need:

  • A cleaner handle look (check the solid handle version)
  • An OTF (out-the-front) mechanism for a different deployment style

5-Hole Handle — Not Just for Looks

The five holes in the handle serve two purposes. First, they reduce weight — this knife comes in at 0.4 lbs, which means it rides easy in your pocket all day. Second, they give your fingers something to grip. When your hands are sweaty, oily, or wet, a smooth handle can slip. The holes create natural finger positions that help you maintain control, especially during repetitive cutting tasks.

The blade is 3.5 inches of stainless steel — long enough to handle real work, short enough to stay practical. The automatic mechanism fires the blade open with one press of the button. The safety lock keeps it from deploying accidentally when it’s in your pocket or clipped to your gear. Collapsed, it’s just 4.5 inches — about the size of your palm.

A no-nonsense automatic knife that works as hard as you do — grab one.

Frequently Asked Questions

What’s the difference between this and the solid handle version?

Same knife, different handle style. The 5-hole handle is lighter and gives you more grip texture. The solid handle has a cleaner look and feels a bit more substantial in the hand. Blade, mechanism, and size are identical.

Is this legal to carry?

Automatic knife laws vary widely — some states allow them, some restrict them, and some cities within legal states have their own rules. Check your local regulations before buying or carrying. Where legal, this is a perfectly practical everyday knife.

How do I maintain the spring mechanism?

Keep it clean and dry. A drop of light oil on the pivot point every few months keeps the action smooth. Don’t force the blade if it feels stiff — that usually means dirt or lint got into the mechanism. A quick blast of compressed air usually clears it right up.
