'Tantos Really F***ing Suck Ass': The Great Tanto Debate Erupts Again on r/knives

Every knife community has a handful of arguments that never die, and the tanto debate is near the top of the list. This week r/knives got a fresh one: a post titled, with admirable directness, 'Tantos really f***ing suck ass.' It is not a nuanced thesis — it is a hot take — and that is exactly why the thread took off. Within hours the comments section was a full-scale debate over blade geometry, cutting performance, and whether the tanto's tactical pedigree earns its keep in the real world.

The anti-tanto case, as laid out in the thread, is well worn but real. The tanto's defining feature — the straight edge that meets the angled tip in a reinforced point — is great for piercing and prying-resistant tip strength, but the flat edge sacrifices the belly that makes a knife a good slicer. For everyday tasks like breaking down cardboard, food prep, and rope work, a drop point or wharncliffe does the job with less effort. Critics also point out that the tanto's tip geometry can make sharpening more fiddly, since the edge angle changes at the transition point.

The pro-tanto side answered with equal energy. The reinforced tip is genuinely useful for penetration-oriented tasks, which is why the shape has roots in Japanese sword design and why tactical and defensive designs — from Cold Steel's classics to modern OTFs — keep using it. Fans argue that the 'tantos can't slice' reputation is exaggerated, that a well-ground tanto cuts fine for most EDC work, and that the look is the point: a tanto simply has more presence than yet another drop point.

What makes threads like this valuable is not the winner — there is no winner — but the breakdown of assumptions. New buyers read the back-and-forth and learn that blade shape is a trade-off, not a hierarchy: the best knife is the one whose geometry matches the tasks you actually do. The thread also produced the usual comedy, with photos of tanto users defiantly slicing apples and drop-point users pretending not to care.

Compared with the calm, spec-driven discussions that dominate most knife subs, the tanto debate is the community's emotional release valve — and it reliably delivers. Whether you carry a tanto every day or think they are a gimmick, this thread has a place in it for you.
