This Unique, USA-Made Utility Knife Deploys an EDC Magic Trick You Need to See

With a mechanically mind-boggling deployment and retraction system, Rivery Manufacturing’s Zero-6061 has kickstarted its way into the mainstream.

A knife is a knife is a knife, right? In the EDC world, as much as we don’t want to admit it, this is usually true. Sure, some designers have reimagine pieces of them — a new locking mechanism here, a twist on a handle format there. But it’s pretty rare for something to emerge that really makes waves. (Just think of the uproar the CRKT Provoke caused when it first came out.)

The Zero-6061 completely reimagines the utility knife concept with a casing that’s entirely free of screws — and really all extraneous hardware. The whole knife consists of just three pieces — a back, a top and a blade housing — and the mechanisms that make it work are built into their design.

Every so often, however, a release comes along that has the potential to change the game entirely. One such item? The innovative, almost entirely hardware-free Zero-6061, boasting a unique deployment mechanism that makes it quite possibly the coolest utility knife we’ve ever seen.

The passion project of Tennessee-based engineer Michael Sayers, this knife first came to our attention in January, when its Kickstarter project absolutely crushed its modest fundraising goal, ultimately raising $114,290 from 1,644 backers.

Since that time, Sayers’s brand itself has evolved — changing its name from Rivery CNC to the more expansive Rivery Manufacturing — and fueled that funding into a wide range Zero-6061 iterations with different handle finishes and colors.

No screws to hold it down

Most utility knives function using the same basic principle: a razor blade is stuck into a slider mechanism, which is then sandwiched (or set) within a handle that’s screwed (or latched) together. There are also those that fold, more like pocket knives, but they’re really not that interesting or innovative, either.

While there’s nothing particularly wrong with these designs — they have worked well for years and years, especially in the shipping and warehousing spaces — there are a lot of parts, which means things can get gunked up or break.

CNC-machined in the USA, The Zero-6061 completely reimagines the utility knife concept with a casing that’s entirely free of screws — and really all extraneous hardware. The whole knife consists of just three pieces — a back, a top and a blade housing — and the mechanisms that make it work are built into their design.

It requires no tools to disassemble, making maintenance (like swapping the blade) super easy. Furthermore, because it’s machined from either 6061 aluminum, you can be sure that it is sturdy as hell (and precise in its construction, to boot).

Part EDC cutting tool, part fidget toy

The Zero-6061 offers intuitive deployment and a mind-boggling retraction system. To extend the blade, you simply slide the top forward until the blade is extended and then slide the top back into place. To retract the blade, pull back on the top, using the ridges for grip, and it snaps the blade back inside the handle.

While it’s not entirely clear how this works, Sayers likens it to “the tricks used inside a mechanical puzzle.” That’s on brand for him — just check out his 2021 Kickstarter project, the less useful but equally enigmatic Impossible Table.

However it works, the system functions brilliantly and invites fidgeting, as you can see in the video above. Feel free to attempt to sort out the secret, or simply savor this bit of practical magic.

Pricing and availability

As big a hit as the Zero-6061 was on Kickstarter, it’s hugely popular on Rivery’s own site now too. Two of its handle styles and one color are currently sold out. However, you can still order the original handle style shown in black or red for $65.

You can also order the Grenade handle style model in gray, black or red for the same price.
