In retrospect I wish I'd divided this into two threads because the term "tactical" is too broad to cover both of what Tom and I are talking about. There is the pure fighting knife that Tom is speaking of, and there is the multifunctional, military capable knife that I'm more familiar with. Both "tactical", but very different.
回想一下，我希望能把这个帖子分成2个，因为“战术”这个词实在太宽泛，不能包含Tom和我说聊的这些。Tom谈的是完全的格斗刀，我更熟悉多功能，军用刀。都“战术”，但是有不同。
In terms of fighting knives Tom's right on, and shivs are probably a great example since they likely kill more people every year than all other knives of any price combined, and are built for concealment, probably with some very ingenious carry systems. Kitchen knives, in addition to being light are also tough by most anyone's standards, designed to be tossed into a sink and have a very thin and fine point survive the experience. Most of them use carbon or stainless steels with ~.40-.55% carbon which brings their hardness to somewhere around Rc45-55. There is a good reason for such hardness. It's more likely to deform than to crack. It can be sharpened or have the edge realigned (if deformed) quickly with a sharpening steel, and the only risk if you drop it on a tile floor is to your foot.
就Tom上面说的格斗刀而言，凶器（shivs）可能是个很好的例子，每年它都比那些为了隐藏而制作，有着独创携带系统的刀杀了更多的人。厨刀，除了轻便，强度也可以满足大多数人的标准。大多数厨刀使用碳钢或者不锈钢，含碳量在0.4～0.55％，硬度在Rc45～55。这样的硬度是有原因的。这样的刀会卷刃，但是不会断掉。它可以很快地用打磨钢棍磨利，修理刃口（如果卷刃了）。唯一的危险就是刀掉在砖地上和你脚上。
It's my understanding that apart from shivs, for which there is likely no data, kitchen knives are those most often used in fatal knife attacks.
这是我对凶器的理解。在那些致命刀具攻击事件中最常用的还是厨刀。
Since we're lifting our skirts a little bit here, I'll add another true confession to the list. How important is edge retention in a fighting knife? Knife fights rarely last more than 5 minutes so I'd guess the answer is you need an edge that lasts... 5 minutes. How long does the edge last on a shiv made from a spoon? Answer: long enough. If you have to sacrifice toughness for edge retention it's a poor trade. That said, the use of high quality steel with a properly formed edge can be vital, but only if you have sufficient toughness to go with it. Fighters can encounter obstacles other than an opponent, including belts, buttons and even an opponent's edge, so if your edge is removed or deformed by such obstacles you then have a dull fighter and that's decidedly not good, but neither is holding a stump of what was once a fancy "tactical zombie eater" . So there are trade-offs in all this that are in the end decided by the balance of attributes you need in a fighting knife, but deciding that balance is something you should contemplate very carefully.
既然在这里要自己揭密，我就再招供一些。一把格斗刀的刀锋的保持性有多重要？格斗的刀很少超过5分钟的持续使用，所以我认识答案就是你需要刀锋的保持性能有5分钟就够了。用汤匙做的刀的刀锋能保持多长时间？答案：足够长。如果你必须牺牲强度来换取刀锋保持性，这个交易不值得。也就是说，一只使用高质量钢材，有着合适刀锋的刀，只有具有足够的强度，才是至关重要的。格斗刀遇到各种障碍比遇到一个敌人的机会要多，包括腰带，纽扣，甚至是敌人的刀，所以如果你的刀被这些障碍物弄得崩刃，卷刃，你的刀就钝了，你就认为这刀不好，但是总比你拿着一把断了的，曾经是华丽的“战术僵尸终结者”要强。所以最后你要面临一把你需要的格斗刀的属性的平衡取舍问题，你需要深思熟虑来权衡这个问题。 |
