Most good projects die by a rough cut. You print a crisp lattice, reach for the hobby knife, and five seconds later, there is a gouge exactly on the outer surface – a part that’s easily visible. That small heartbreak is what HOZO Design set out to delete with NeoBlade, a cordless cutter that trades brute force for forty-thousand-times-per-second ultrasonic finesse. The idea is simple: let vibration slice through projects with the perfection of a knife through room-temperature butter.

NeoBlade looks and feels like a chunky marker that fits perfectly into your grip. Battery clicks into the tail, blade peeks from the nose, and the whole tool tips the scale at 6.4 ounces, so even a long session of trimming support material will not sprain a wrist. Press the trigger gently, and Precision mode fires in quick bursts, perfect for knocking a single nub off a resin mini. Pull past the detent, and Continuous mode hums until you let go, turning foam board or acrylic sheet into respectful, silent ribbons. A perfect gizmo for finishing touches on all your projects.

Forty kilohertz of motion means the edge never drags long enough to melt plastic or splinter wood. Instead, it slips forward under light pressure, one microscopic slice after another, leaving a glassy face that looks almost molded. A smart driver reads resistance on the fly and feeds anywhere from nine to forty watts to the actuator, so switching from soft PLA to stubborn ABS feels seamless. There is no temperature dial to chase, no speed knob, no guesswork.

Keeping the tip cool is the job of a tiny turbofan buried in the barrel. Air enters through side vents, slides across the metal core, and exits behind your hand, dropping blade temperature far below the scorch line of common filaments. The handle stays comfortable, the cut stays clean, and warping never starts. Two bright LEDs flank the blade to fill shadows that magnify mistakes, a small but welcome nod to late-night builds.

HOZO ships six blade profiles in snap-forward cartridges. A 30-degree spear handles everyday trimming, a longer spear dives deeper stock, a curved slice glides through vinyl and leather, a twin-edge scores parallel grooves, and two chisel tips tackle carving and cleanup. Used blades press into a one-way slot on the cartridge, so they retire safely instead of migrating to a drawer where future you will forget they exist. The tool cap hides a stubby driver and a magnet that holds the fresh blade steady while you line up the tang, a little UX grace that feels earned on a cluttered bench.

Changing the Battery

The NeoBlade Creator Combo includes the TurboDock, an extra Battery Pack, and a set of trial blades

Cordless convenience lives or dies by downtime, so NeoBlade ships with an optional TurboDock that charges the handle and a spare cell in about thirty minutes. Slide one battery out, slide the other in, twist, and you are back to slicing before the printer’s next layer cures. Makers on a tighter budget can rely on the USB-C port in the grip, though that route parks the cutter for an hour or more. Early Kickstarter pledges locked in the full kit for $99 USD, a tidy slice off the planned $149 retail tag. The Creator Combo (priced at a discounted $149) packs the NeoBlade, a TurboDock, an extra battery, and a spare blade trial kit with 6 blades.

But don’t confuse this with one of those cheap cutters on Amazon or that soldering iron that you also use to burn off imperfections in 3D prints. Because the edge oscillates instead of tearing, you avoid the fuzzy bead that hot-wire cutters leave in foam and the ragged fringe delivered by abrasive wheels. Clean edges mean less post-processing, which in turn means more time for tuning the slicer profile or experimenting with paint. Model makers, cosplay armor builders, prop shops, even electronics hobbyists who need to notch an enclosure without filling the room with ABS dust will notice the difference on day one.

NeoBlade lands at a sweet spot between pocketable craft knives and industrial ultrasonic stations that never leave a lab. It gives hobbyists, cosplay armor fabricators, prop builders, and small-batch product designers a push-button guarantee of clean edges and repeatable results. By making ultrasonic cutting as casual as clicking a pen, HOZO turns the most stressful step of fabrication into the easiest. Projects move forward, sanding blocks stay clean, and the next big idea arrives sooner because the last one didn’t stall at the trimming stage.

Seatbelts are designed to not be cut. Glasses on cars are designed to not be broken. That’s all well and great until you find yourself in an emergency where you need to get out of a car and you’re stuck because of a jammed seatbelt or door. Although seatbelts and laminated glass panels are designed effectively to protect you, they can sometimes become the barriers to your safety – which is why it helps to have something like the Lifehammer Smart Automatic on you. A little larger than an AirPods case, the Lifehammer Smart Automatic is an emergency tool that helps you quickly slice through seatbelts and shatter glass windows so you can make an exit in a scenario where every second matters to your safety. Designed to be the essential EDC that every car needs, this $25 gadget could literally be a life-saver.

The Lifehammer Smart Automatic has a pretty compact, self-explanatory design, which makes it perfect for intuitive use in a split-second emergency. The soap-shaped gadget is easy to grasp firmly in your palm, and comes with a cutout on the side that you hook around your seatbelt. Slide the device over and it slices through the seatbelt’s tough fibers like a knife through butter… while still maintaining a safe design that won’t ever accidentally hurt you.

The top of the Lifehammer Smart Automatic houses its glass-breaker tip. It’s easy to identify the two crucial features simply by looking for the orange accents which highlight the cutter and breaker respectively. The top of the Smart Automatic has a spring-loaded head that you simply press into a glass panel. Eventually, it triggers the glass-breaker tip to eject outwards and shatter any tempered or laminated glass – like the ones found on car windows and windshields. The process requires minimal effort and time, allowing you to quickly break through the glass in case your door gets jammed.

A winner of this year’s iF Design Award, the compact Lifehammer Smart Automatic is a lot smaller than most car-safety gadgets we’ve seen, and comes with its own holder that attaches to any part of your car using 3M adhesive tape. This means you can attach the Smart Automatic beside your seat or the gearbox, or even behind the rearview mirror so it’s easier to access than having to open the glove box and fish around.
