I don't care who the fighter is or how skilled they are they're going to be polar bear dinner. First off polar bears have an extra layer of fat around their already substantial fur. I doubt very seriously if any average pocket knife can even get through the fat layer to a vital organ. Even if that man was skilled with a knife and had a full-fledged bowie knife. He would have to be extremely extremely lucky to hit an organ quick enough to kill the bear before the bear killed him. So no I would bet every dollar I have ever made in my life that that polar bear is going to win that fight 100 out of 100 times.

我不在乎拳击手是谁，也不在乎他们的技术有多熟练，归根结底他们将成为北极熊的晚餐。首先，北极熊那已经很结实的皮毛周围有一层加厚的脂肪。我严重怀疑，一把普通的小刀是否能穿过北极熊脂肪层并攻击到它的重要器官。即便那个人很会用刀，而且手里有一把锋利的猎刀。在北极熊杀死他之前，他必须非常幸运地以足够快的速度击中北极熊的致命器官杀死熊。所以，答案是不，而且我敢打赌，用我这辈子赚的每一美元打赌，那只北极熊都会在那场战斗中百分百获胜。

Polar Bears are enormous.
When they stand on their rear legs, they can look in second story windows.
Their skull is harder and thicker than a motorcycle helmet.
They kill seals just by slapping them.
I give the fighter 180 seconds.
Here’s a black bear, a grizzly, and a polar bear:

北极熊体型巨大。
当他们用后腿站立时，他们可以平视二楼的窗户。
他们的头骨比摩托车头盔更硬更厚。
他们只需抽海豹耳光就可以杀死海豹。
我的答案是：拳击手能在北极熊手上存活180秒。
这是一只黑熊、一只灰熊和一只北极熊的比例图：

The human might have a chance of surviving if either of the following is true.
One is that the pocket knife is attacked to a rather large gun, the gun is loaded, the human knows how to use it, and the human has time to get a shot or two off and manages to hit a critical part of the bear.
The other is that the pocket knife is in a car, and the human is inside the car along with the pocket knife with the doors shut. Apparently polar bears rarely bother to smash up a car to get the food (the bears name for what we would call a human) out of the car.
Otherwise the human would be alive for a few seconds. If the bear is feeling kind, he might knock your head off before he starts to eat you.
If the human is particularly large, athletic, strong and muscular, the muscles would provide more protein for the bear’s dinner.

如果以下任一情况成真，人类就可能有机会存活。
一是把小刀用一把相当大的枪替换掉，枪已上膛，并且那名人类知道如何使用它，人类有时间开一两枪，并设法击中熊的致命要害。
另一种情况是是小刀在车里，人和小刀都在车里，车门都关着。显然，北极熊很少会为了从车里取出食物（北极熊给人类起的名）而砸车。
其他任何情况下，人类都只能活几秒钟。如果那头北极熊很上流优雅，他可能会在吃你之前把你的头敲掉。
如果那人特别高大、经常运动、强壮并且肌肉发达，那么那些肌肉会为熊的晚餐提供更多的蛋白质。

Not long at all. There’s not a martial art in the world that’s effective against any kind of bear let alone a Polar Bear. Polar Bears are the most aggressive, most territorial, meanest bear there are. They will kill and eat other Polar Bears for encroaching on their territory. A pocket knife?!? Really?!? Just one of a Polar Bear’s paws is equipped with claws the size of full hunting knives. They outweigh even the most muscular human by hundreds of pounds, they’re faster and stronger than any Olympic athlete. The human has zero chance of making it out alive, if they’re lucky, the bear will make it a quick death.

他会死的很快。世界上没有一种武术能用来对付任何熊，更别说北极熊了。北极熊是最具侵略性、最具领土意识、最卑鄙的熊。他们将杀死并吃掉其他侵占其领土的北极熊。一把小刀？！？真正的北极熊一只熊掌上有一把猎刀那么大的爪子。他们甚至比肌肉最发达的人重数百磅，比任何奥运会运动员都快，也更强壮。人类活下来的几率为零，如果幸运的话，它会给你个痛快的死法。

A pocket knife??
Let me tell you a story I heard about a New Yorker who decided to go camping up in Grizzly country. He thought he should get some protection first, so stopped in at a gun store. After looking around for a while, the guy asked the owner:
“Hi, could you tell me which handgun is best in case of Grizzly attack?”
The owner peered over his glasses and replied:
“Why, pick any one you like son, but whatever one you pick just make sure to file the front sight down real smooth.”
“Why?”
“Cos that way it won’t hurt too much when the bear takes it off you and shoves it up your ass!”
The point being that to reliably take out a Grizzly bear, you need a high powered rifle or shotgun. Now how does a Grizzly compare to a Polar Bear?
Yeah
So no, a Human (any human) could not kill a Polar Bear with a pocket knife. Your best bet is to use the knife to stab the guy next to you and run the hell away.

一把小刀？？
让我给你讲个我听来的笑话，一个纽约人决定去灰熊出没的地方露营。他认为自己应该先武装起来，所以在一家枪店门口停了下来。在四处看了一会儿后，这家伙问店主：
“嗨，你能告诉我哪把手枪最适合面对灰熊袭击吗？”
店主透过眼镜看了看，回答道：
“讲真，小兄弟，随便选一把你喜欢的，但无论你选哪一把，都要确保前面的枪膛很平滑。”
“为什么？”
“因为这样，当熊把它从你身上抢下来，塞进你的屁股时，你就不会太疼了！”
关键点是要想哪怕干掉一只灰熊，你都需要一支高威力的步枪或猎枪。而灰熊和北极熊相比又是怎么样的呢？

就是这样
所以，人类（任何人类）都不能用小刀杀死北极熊。你最好的办法就是用刀刺伤你的同伴然后独自逃走。

Assuming they start out by standing close enough for the human to reach the polar bear, about 2 seconds.
If the human has a pocket knife, that’s a crunchy bit to the bear.
There’s simply no realistic way for a human to survive an encounter with a polar bear, unless the human has a good hunting rifle and spots the bear from a bit away. Whether the human is the strongest or the weakest human on the planet is immaterial; the strongest human in the world is considerably weaker than the weakest polar bear in the world.

假设他们一开始就站得离北极熊足够近，他们大概能活个2秒钟。
如果人类有一把小刀，那对熊来说就是一块松脆的小饼干。
人类要想在与北极熊的遭遇中幸存下来，根本没有现实存在的方法，除非人类有一把上好的猎枪，并能从远处发现北极熊。那个人类是地球上最强壮的还是最弱的人都无关紧要；世界上最强壮的人要比世界上最弱的北极熊弱得多。

A pocket knife? Really?
That fighter isn’t killing that bear. There’s no question there. The moment blow comes to blow, that fighter’s life is finished.
Really, the best the fighter can hope for is to escape this encounter. I’ve heard that the thing to do with polar bears is to drop a piece of clothing or something that you’re carrying. Polar bears are inquisitive animals and they’ll stop and examine it, giving you time to put some distance in between the bear and you. If it comes after you again, you drop another piece of clothing. Repeat until you’re either out of danger, or you freeze to death from lack of clothing.
Please note that the above is the kind of advice that’s difficult to test in real life, so individual results may vary.
Having a car nearby can also change the odds of survival in your favor, even if the car isn’t turned on. A bear can outrun a human, but not around a large car or truck! Bipedal humans are a lot better at turning than our four-legged friends, and going around a car is basically a way of changing a speed contest into a turning speed contest. Sooner or later, it’ll get frustrated and tired of the chase, allowing you to get into the car and drive away. Just don’t make any mistakes before that happens.
Don’t fight polar bears. You’ll lose.

一把小刀？你在搞笑吗
那个拳击手不可能杀死那只熊。这是毫无疑问的。当北极熊的熊掌拍来时，那个家伙的生命就此结束了。
真的，拳手们最希望的就是逃离这次遭遇。我听说对付北极熊的办法是扔下一件衣服或你随身携带的东西。北极熊是好奇的动物，他们会停下来检查你丢下的东西，这能帮助你在熊和你之间留出一些距离。如果它再次追上你，你就扔下另一件衣服。重复上述步骤，直到你脱离危险，或者你因缺乏衣物而冻死。
请注意，上述建议在现实生活中很难保真，因此每个人的结果可能会有所不同。
附近有一辆车也可以提升你的存活几率，即使车门没有打开。熊跑得比人快，但踏不能绕着大汽车或卡车跑！两足动物的转弯能力比四足动物要好得多，绕着汽车转基本上是一种将直线竞速赛转变为弯道竞速赛的方式。最终，北极熊会对追逐感到沮丧和厌倦，你就能上车离开。在那之前确保不要犯任何错误。
不要试图与北极熊搏斗。你输定了。

I feel in blades nothing less than a great sword (freshly sharpened) would be required to put a stop to a polar bear, wielded by someone skilled in it’s use and large enough to produce a very heavy stroke.
You’d only get one swing and it would need to be strong enough to create a massive injury in the bear. The pocket knife may as well be a toothpick, a pro fighter doesn’t last any amount of time with or without a pocket knife lol. Well the time it takes for the bear to maul him to death, but he’s off his feet helpless under the bear as soon as the bear makes contact.
From what I’ve heard, in the old colesseum matches when bears got to 1,000+ lbs they beat fighting bulls more often than not, bears under 1,000 lbs would lose more often than not to fighting bulls. A 1,100 lb male polar bear is a literal monster, way worse than a lion or tiger.
I’m not a sword person but it seems like even a longsword doesn’t have the weight behind it to create a large enough wound. The polar bear needs to weaken and succumb within about one minute after the wound is delivered or the person will be dead from the mauling. This will require a massive crippling wound, which I feel would require a heavier stroke than we realize. Even on a human you probably don’t cut a person in half with a great sword without a mighty stroke.
Even in the hands of a large strong skilled great swordsmen I feel it wouldn’t work most times, to put a square heavy stroke like that on a charging bear would be hit and miss. But it’s a chance.

我觉得如果给你的刀要能够阻止一头北极熊，最可能的武器就是一把巨剑（开刃），由熟练使用它的人挥舞，剑的大小足以令它造成非常沉重的一击。
你只有一次机会，而这刀必须足够强力，才能在熊身上造成巨大的伤口。小刀就像是牙签，职业拳击手无论有没有小刀都不会对结果造成任何影响。哈哈，他存活的时间甚至会少于熊把他咬死所需的时间。
据我所知，在古罗马的斗兽比赛中，当熊体重超过1000磅时，他们会经常击败斗牛，而1000磅以下的熊会经常输给斗牛。一只1100磅重的雄性北极熊是一种真正的怪物，比狮子或老虎还要离谱。
我不是一名用剑的选手，但似乎连一把长剑都没有足够的重量来制造一个足够大的伤口。北极熊需要在伤口撕开它的躯体后一分钟内变弱并屈服，否则人类将因伤势过重而死亡。这将需要一条巨大的撕裂伤，我觉得这需要比我们能想象得到的最重的一击还要重。即使是面对一个人类，你也做不到在没有足够强力一击的情况下用一把巨剑将一个人砍成两半。
而这把武器即使是在一个身强力壮、技艺高超的大剑客手中挥舞，我也觉得大多数时候都不管用，像这样往一头向你冲来的熊挥砍，你依然可能砍不中。但无论如何，这是一个活命的机会。
