The 5-hole cutout handle reduces weight without sacrificing grip, and the safety lock keeps it closed until you're ready.

- 3.5" blade with 8" overall length — a useful size that's not excessive
- 5-hole stainless steel handle — reduces weight, improves grip
- Safety lock — keeps the blade secured when closed
- Compact collapsed length of 4.5" — fits a pocket or clip without bulk
A Knife That Opens When You Need It To
There’s a reason automatic knives have been around forever — when you need a knife fast, you need it fast. This one has a clean, positive deployment with a side-button mechanism that’s easy to find by feel. The 3.5-inch blade is a practical length: enough to be genuinely useful, not so long that it’s awkward to carry or store.
The 5-hole handle is a classic design that’s been used on quality knives for decades. The cutouts lighten the handle without weakening it, and they give your fingers natural indexing points. This is a stainless steel handle, not plastic — it has some weight and solidity to it that cheaper knives lack.
Who This Knife Is For
This is a good fit for someone who wants a reliable automatic knife for everyday utility — opening boxes, cutting rope, general use around the house, job site, or camp. The fast deployment makes it more practical than a traditional folding knife when you’ve only got one hand free.
It also works well as a backup carry piece for people who already have a primary tool on them and want something that opens quickly without fumbling. The safety lock is a genuine feature, not an afterthought — it holds the blade closed reliably so you’re not worried about it opening in your pocket.
Is This the Right Choice for You?
Choose this automatic knife if you want:
- Fast one-handed blade deployment for utility or self-defense
- A solid stainless steel handle that won’t flex or rattle
- Classic 5-hole design that’s comfortable and well-balanced
- A dependable safety lock that actually holds
Consider something else if you need:
- An OTF (out-the-front) mechanism — this is a side-deploy folder
- A longer blade for heavy-duty cutting tasks — 3.5″ is a moderate utility length
How It Actually Works
The side-button deployment is straightforward. Disengage the safety, press the button, the blade swings out and locks open in one motion. It’s fast enough that you won’t be fumbling when you need it. The lock-back mechanism holds the blade firmly open during use — no flex, no wobble.
At 0.4 lbs total, it’s light enough to pocket-carry comfortably. The 4.5-inch collapsed length means it doesn’t add much bulk to a pants pocket or jacket pocket. The black finish on the handle and blade keeps it looking clean even with regular use.

Frequently Asked Questions
Are automatic knives legal to own and carry?
Automatic knife laws vary significantly by state and sometimes by city or county. Some states allow ownership but restrict carry length. Others have broader restrictions. Before purchasing, check the specific laws in your state and any locality you intend to carry in. A quick search for your state’s automatic knife laws will give you current, specific information.
What’s the difference between the 5-hole handle and the solid handle version?
Functionally they’re the same knife — same blade, same mechanism, same dimensions. The 5-hole handle has cutouts in the stainless steel that reduce a small amount of weight and give your fingers natural grip points. The solid handle gives you a full-contact grip surface. It mostly comes down to personal preference and which feel you prefer in hand.
How does the safety lock work?
The safety lock keeps the blade from deploying accidentally when the knife is in your pocket or bag. You disengage it before pressing the deployment button. It’s a simple mechanism that doesn’t require a lot of thought, but it does add a meaningful layer of security for everyday carry. The blade also locks open during use so it won’t fold back on your hand.
