The TNT Knives Slip Bang Has Four Legal Carry Configurations

Most knife owners treat blade laws like weather: something you check before you leave, then hope for the best. Pack a locking folder for a weekend in London, feel the weight of it settle in your jacket pocket, and you’ve already miscalculated. Carry a one-handed locking folder through Germany and you’re technically breaking the law, even if nobody stops you. That quiet gamble runs through the whole EDC community, and it rarely gets an engineering answer because the issue isn’t the knife.

So the real question is: what if the knife could adapt to the law instead of the other way around? That’s the pitch behind the TNT Knives Slip Bang, a titanium-framed folder built around four legal configurations that swap with a standard Torx driver. Maxi Haensch launched the Kickstarter from Hamburg, where Knife Lounge operates alongside the Altonaer Silberwerkstatt, a silversmithing workshop with roots in metalwork. Backers pushed the campaign to €54,637 ($64,703) on a €15,000 goal ($17,761), 364% funded from 160 pledges, with delivery estimated for June 2026. We Knife, the parent company behind Civivi, is handling production, the kind of partner that turns a Kickstarter knife into something you’d trust in your pocket. Germany’s knife laws rank among the strictest in Europe, and that’s the pressure this idea grew from.

What It Is

Four modes live inside one frame, and each addresses a different legal ceiling. At its most limited, the Slip Bang works as a two-handed non-locking titanium slip joint knife, the kind of folder you can carry almost anywhere on the planet without a second thought. Add thumbstuds to the blade and it becomes a one-handed opener, swap the handle inlays for a slider and the knife gains a lock, or combine both for a one-handed locking folder that performs like most modern EDC knives.

The swap keeps things deliberately low-tech. You pull the existing hardware, drop in the replacement, tighten a few Torx screws, and the knife behaves differently. No special bits, no snap-fit parts that wear out. Blade steel is CPM-20CV, which holds a working edge longer than most at this price and resists corrosion without babying. Grade-5 titanium makes up the handle, the same metal found in aircraft parts and high-end watch cases. Fully deployed, the knife stretches to 7.8 inches and weighs just under four ounces. If you’ve carried a mid-size titanium folder, you know the feel: cool to the touch, heavier than you expect, with a solid density cheaper materials can’t match. A new locking mechanism called TNT-Lock rounds out the build, and with We Knife behind execution, the lockup should be clean across every mode.

One detail worth flagging: the blade stays the same across all four setups. Only the deployment method and locking behavior change, which means this configurable pocket knife keeps the same edge geometry, grind, and steel performance regardless of mode.

CPM-20CV isn’t a flashy steel choice, and that’s the point. It runs with more predictability and a longer track record than newer options like Magnacut or S90V. For a CPM-20CV knife meant to cross borders, reliability matters more than peak hardness. The titanium handles repeated hardware swaps without deforming around the screw holes. Every material choice prioritizes function over flash. The build philosophy favors tools that work everywhere over showpieces that impress once.

That blade length clears most U.S. city carry limits, where the common cutoff sits around 3.5 or 4 inches. Stricter European laws might flag it, but the slipjoint and non-locking setups exist for those environments. It’s a legal carry knife that stretches as far as possible without shrinking into novelty territory. Each version fills a legal gap, and transitions take seconds.

Who Should Skip This

At $413 (€349) for the early bird tier, the Slip Bang sits in premium EDC territory. That price makes sense when you factor in CPM-20CV, grade-5 titanium, We Knife production, and the engineering cost of four setups in one knife. But if you carry the same knife in the same city every day, you’re paying for versatility you won’t use. A dedicated locking folder at the same price will feel tighter and more refined because it only needs to do one thing. The modularity tax is real. Kickstarter delivery timelines always carry risk, and the June 2026 window isn’t guaranteed. If you need a knife now, this isn’t it.

There’s also the question of long-term parts. Spare hardware ships with eligible pledges, but what happens five years out when you strip a screw or lose an inlay? TNT Knives hasn’t addressed that yet.

Collectors who want a fixed configuration that never changes should look elsewhere. The same goes for anyone uncomfortable with Torx disassembly as part of regular carry. If you’re the kind of carrier who picks one knife and doesn’t touch the hardware for years, the Slip Bang’s main feature becomes dead weight. It’s a tool for people who move. If you don’t, simpler options exist.

Who This Is For

Frequent travelers who cross borders with different blade laws will feel the Slip Bang’s value immediately. Carrying one knife that adjusts to each set of rules beats packing three or leaving your best folder at home.

EDC enthusiasts who rotate knives based on context will appreciate one platform that shifts to match the situation. The engineering appeal is real too. If you care about how things work, not just how they cut, the swap system invites hands-on engagement that fixed-design knives can’t offer. There’s a ritual quality to changing setups: selecting the mode, reaching for the Torx driver, feeling parts seat into position. It’s closer to maintaining a mechanical watch than swapping a phone case. For anyone tracking the intersection of knife law and EDC design, this release is part of the conversation about where the category goes next.

At this price, with this level of manufacturing behind it, the Slip Bang is one of the more interesting modular EDC knife releases of 2026. It won’t replace a purpose-built locking knife for someone who only needs one mode. But for carriers who’ve felt the friction of crossing a border with the wrong blade, this is the first serious attempt at making one knife work everywhere.

That convenience carries a cost, and $413 (€349) reflects it. The math works differently when you’ve already lost a knife to a customs bin or had to leave a favorite blade in a hotel safe. This knife doesn’t settle the question of what a modern EDC knife should be. It makes the discussion more interesting. That’s a harder problem than most brands bother trying to solve.
