SKU ST-AK-101 Categories ,

Original price was: $18.95.Current price is: $16.11.

I compared a lot of knives before settling on what actually makes sense for everyday carry — and a few things kept coming up: reliable deployment, a solid grip, and a safety lock you can actually trust. This one checks all three. The 5-hole handle gives you real grip control, and the safety lock keeps it where it belongs until you’re ready.

  • Automatic side-opening deployment — blade opens quickly and consistently with one hand
  • 3.5-inch blade with 8-inch overall length — practical size for everyday tasks
  • 5-hole stainless steel handle — reduces weight while improving grip
  • Safety lock included — prevents accidental deployment when carried
  • Compact at 4.5 inches collapsed — fits a pocket, bag, or belt clip without bulk

A Solid Everyday Carry That Actually Deploys When You Need It

I spent some time looking into automatic knives before writing this up, and the thing most people care about is simple: does it open reliably, and does it feel solid in your hand? This one does both. The side-opening automatic mechanism is consistent, and at 0.4 lbs, it’s light enough to carry all day without noticing it.

The 5-hole handle design is a practical choice — it cuts down on weight while giving your fingers something to grip. Combined with the safety lock, you get a knife that stays put until you decide to use it.

Who This Automatic Knife Is For

This knife works well for anyone who wants a dependable everyday carry without a lot of fuss. If you use a knife regularly for utility tasks — opening boxes, cutting cordage, food prep at a campsite — the automatic deployment makes one-handed use genuinely convenient.

It’s also a reasonable choice for someone who wants a backup tool for self-defense situations. The quick deployment matters when you need it fast, and the safety lock means you don’t have to worry about it opening in your pocket. People who work outdoors, camp frequently, or just want something more capable than a basic folding knife tend to find this category useful.

One thing worth knowing upfront: automatic knives are restricted or prohibited in some states and localities. Check your local laws before purchasing.

Is This the Right Choice for You?

Choose this automatic knife if you want:

  • Fast, reliable one-handed deployment for utility or self-defense use
  • A lighter carry with the 5-hole handle design
  • A safety lock that prevents accidental opening in a pocket or bag
  • A mid-size blade that handles everyday tasks without being oversized

Consider something else if you need:

  • A manual folding knife (legal in more places without restriction)
  • A longer blade for heavy-duty cutting tasks

How It Actually Works

The side-opening automatic mechanism means the blade deploys with a button press — no two-handed fumbling, no nail nick required. That’s the practical difference between an automatic and a standard folder. When you’re wearing gloves, working with one hand, or just need it out quickly, that matters.

The stainless steel handle with 5 holes keeps the overall weight at 0.4 lbs, which is noticeably lighter than solid-handle knives of the same size. The holes also give your grip something to register against, which helps with control during use. The safety lock is a simple mechanism — engaged, the blade won’t open. Disengaged, it’s ready to deploy.

At 3.5 inches, the blade is long enough for most utility tasks and meets the legal blade length limit in many jurisdictions — though again, the automatic mechanism itself is the main legal consideration to check in your area.

Frequently Asked Questions

Is this knife legal to carry where I live?

Automatic (switchblade) knives are regulated differently depending on where you are. Some states allow them freely, others restrict blade length or require a permit, and some prohibit them entirely. Before purchasing, look up your specific state laws and any local ordinances. This is genuinely worth doing — it only takes a few minutes and saves a real headache later.

How does the safety lock work?

The safety lock is a mechanical switch that prevents the blade from deploying when engaged. With the lock on, pressing the release button does nothing — the blade stays closed. Slide the lock off, and the knife deploys normally. It’s a straightforward design that makes carrying in a pocket or bag much more practical.

What’s the difference between the 5-hole handle and a solid handle?

The 5-hole handle (ID 21832) is lighter and has slightly more grip texture because of the cutouts. The solid handle (ID 21833) has a smoother profile and may feel more substantial in hand. Both have the same blade length and overall dimensions. It mostly comes down to personal preference — some people like the lighter feel, others prefer the solid construction.

What’s the blade made of?

The blade is premium quality steel — durable enough for regular use and able to hold an edge with normal maintenance. For best longevity, rinse and dry the blade after exposure to moisture and store it with the safety lock engaged. The stainless steel handle resists corrosion well under normal conditions.
