Streetwise Automatic Heavy Duty Knife 3.5″ Blade – Solid Stainless Steel Handle, Safety Lock, 8″ Overall Length, Side-Opening Automatic Deployment

SKU ST-AK-102 Categories ,

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

Same reliable side-opening automatic mechanism as the 5-hole version, but with a solid stainless steel handle for a more substantial feel in hand. If you prefer a smooth, clean profile without cutouts, this is the one to look at. The safety lock and 3.5-inch blade are identical — it really comes down to how you want it to feel when you’re holding it.

  • Automatic side-opening deployment — consistent one-handed blade access with a button press
  • 3.5-inch blade with 8-inch overall length — practical everyday carry size
  • Solid stainless steel handle — smooth, substantial feel with no cutouts
  • Safety lock included — blade stays closed until you’re ready
  • 4.5 inches collapsed — fits a pocket without adding bulk

Same Fast Deployment, Solid Handle for a More Substantial Grip

The main difference between this knife and the 5-hole version comes down to handle preference. This one is a solid stainless steel handle — no cutouts, no holes, just a clean profile that feels more substantial when you’re holding it. The automatic deployment, blade length, and safety lock are the same on both. If you’ve handled both types and prefer the solid feel, this is your knife.

At 0.4 lbs, it’s still a light carry despite the solid construction. The side-opening automatic mechanism is consistent — button press, blade deploys, ready to use.

Who This Automatic Knife Is For

This version tends to appeal to people who want their knife to feel more like a traditional tool — solid and predictable in hand. If you’re used to fixed-blade or traditional folding knives and find cutout handles feel a little hollow, the solid handle is the better fit.

It works well for daily utility use: camping, outdoor work, general cutting tasks where one-handed deployment is a genuine convenience. It’s also a reasonable self-defense backup for situations where speed of access matters. As with any automatic knife, check your local laws before carrying — regulations vary widely by state.

Is This the Right Choice for You?

Choose this automatic knife if you want:

  • A smooth, solid handle feel without cutouts
  • Fast one-handed deployment for everyday carry or utility use
  • A safety lock that prevents accidental opening
  • A mid-size blade at a practical carry length

Consider something else if you need:

  • A lighter carry — the 5-hole handle version saves a small amount of weight
  • A manual folding knife with fewer legal restrictions

How It Actually Works

Press the button, blade deploys — that’s the core function of an automatic knife. No nail nick, no two-handed opening, no fumbling when you’re wearing gloves or working with one hand occupied. The side-opening mechanism on this knife is reliable and consistent, which is the thing that matters most with an automatic.

The solid stainless steel handle provides a firm, even grip surface. Some people find this preferable to cutout handles because the contact area is consistent across the whole grip — no fingers landing in a hole by accident. The safety lock is a straightforward slide mechanism: engaged means locked, disengaged means ready.

Collapsed at 4.5 inches, it fits in a front pants pocket or jacket pocket without printing noticeably. The 3.5-inch blade length sits within the legal limit for blade length in many jurisdictions, though the automatic mechanism itself is the primary legal variable to research in your area.

Frequently Asked Questions

How is this different from the 5-hole handle version?

The only difference is the handle design. This version has a solid stainless steel handle with no cutouts. The 5-hole version has the same blade and mechanism but a lighter handle with cutouts that provide slightly more grip texture. Blade length, overall dimensions, safety lock, and deployment mechanism are identical on both. It’s purely a feel preference.

Is this knife legal to carry?

Automatic knives (also called switchblades) are regulated differently from state to state and sometimes by city or county. Some places allow them without restriction, others limit blade length or require a specific purpose, and some prohibit them entirely for civilian carry. It’s worth spending a few minutes checking your state’s knife laws and any local ordinances before you order.

How do I maintain this knife?

Basic knife maintenance applies here: keep the blade dry, wipe it down after use, and apply a light coat of oil occasionally to prevent corrosion on the blade. The stainless steel handle holds up well to normal use. Avoid submerging the knife in water, and periodically check that the safety lock engages cleanly. If the mechanism starts feeling stiff, a small drop of knife oil at the pivot point usually helps.

What is the blade steel?

The blade is made from premium quality steel designed for durability and edge retention under regular use. It’s not a specialty steel marketed toward collectors or professional chefs — it’s a working blade meant to hold up to everyday tasks. Keep it reasonably dry and give it an occasional touch-up on a sharpener, and it’ll stay functional for a long time.
