A Solid Automatic Knife That Does What It’s Supposed To
Some knives you buy and end up not carrying because they’re too bulky or the mechanism feels cheap. This one sits at 0.4 lbs and 4.5 inches closed — fits fine in a front pocket. The blade deployment is smooth, the safety lock is easy to work with one thumb, and the stainless steel handle feels like it’ll hold up over time. For under twenty bucks, it’s honestly a pretty good deal.
Who This Automatic Knife Is For
If you just want a reliable everyday carry knife that opens fast and doesn’t cost a lot, this is a reasonable pick. It’s practical for folks who use a knife regularly — utility tasks, camping, fishing, general EDC. The one-handed deployment is useful when your other hand is occupied.
It’s also a decent option if you’re looking to replace a folder that’s been giving you trouble. The safety lock makes it safe to pocket without worrying about the blade working loose. Good for someone who wants automatic action without spending serious money.
Is This the Right Choice for You?
Choose this automatic knife if you want:
- Fast one-handed blade deployment for everyday carry
- A secure grip with the 5-hole handle design
- Safety lock for worry-free pocket carry
- An affordable automatic knife under $20
Consider something else if you need:
- A longer blade for heavy-duty work — 3.5 inches has limits
- OTF (out-the-front) deployment style — this is a side-opening automatic
How It Actually Works
It’s a side-opening automatic — press the button on the spine and the 3.5-inch blade snaps out fast. The motion is clean, not sloppy. Lock it back with the safety before you pocket it and you’re good to go. The 5-hole handle design isn’t just aesthetic — those cutouts reduce weight and give your fingers natural purchase on the grip.
The stainless steel construction keeps things simple: easy to clean, holds an edge reasonably well, and the black finish doesn’t show wear quickly. At 8 inches open and 4.5 closed, it’s a practical size — big enough to be useful, small enough to carry without thinking about it.

Frequently Asked Questions
Is this knife legal to carry in my state?
Automatic knife laws vary significantly by state and sometimes by city or county. Some states have length restrictions or outright bans on automatic knives. Before carrying this knife, check your local and state laws to make sure you’re in compliance. When in doubt, contact a local attorney or check your state’s current statutes on automatic knives.
What’s the difference between this knife and an OTF automatic?
This is a side-opening (or side-deploy) automatic knife — the blade pivots out from the side of the handle when you press the button, similar to a switchblade. An OTF (Out the Front) knife fires the blade straight out the front end of the handle. Both are fast one-handed deployments, but the mechanisms and feel are different. OTF knives tend to cost more. This one’s the more traditional automatic style.
Does the safety lock actually hold in a pocket?
Yes — the safety lock is designed to keep the blade from deploying accidentally while the knife is in your pocket or bag. It’s a simple mechanism: engage the safety before pocketing it, disengage when you need it. I’ve found it reliable. It’s one of the main reasons to choose an automatic over a manual folder for pocket carry.
How do I maintain the blade?
Wipe down the blade after use to prevent corrosion, especially if it’s been exposed to moisture. A light coat of oil on the blade and around the pivot keeps the deployment smooth over time. Sharpen as needed with a standard knife sharpener. The stainless steel holds up well with basic care and doesn’t require anything complicated.
