家居生活Laser Knife Edge Reader 激光刀刃测量器,专测刀的锋利度或钝度

2020-01-02  5400

如果手头上有适当的工具,则削钝刀就很容易了。但是,每次将其始终保持为相同的水平是很难得事,因为要获得客观的边缘锐度并不是一件容易的事,Laser Knife Edge Reader 想要更改它。

Sharpening a dull knife is easy enough if you have the proper tools on hand. Sharpening it to the same level consistently every time, though, is another matter entirely, since it’s not really easy to get an objective measurement of the sharpness of an edge. The Laser Knife Edge Reader wants to change that.

这是一种手持式工具,可让您测量放置在刀片上的刀刃的角度,它为确定刀的锋利度提供了客观标准。这样,如果您需要以能产生完美切割效果的方式锐化刀片,则可以对其进行测量,并在下次处理其边缘时尝试达到相同的角度。

A handheld tool that lets you measure the angle of the edge you put on the blade, it gives you an objective criteria for determining a knife’s sharpness. That way, if you sharpen a blade in a way that produces the perfect cuts, you can measure it and try to achieve the same angle the next time you work on its edge.

Laser Knife Edge Reader 是一种简单但巧妙的设计,它使用激光指示器将光投射到您的刀上,然后将光反射到刀前的角度。您将读数取到左侧,将读数取到右侧,然后将它们加起来即可得到刀刃的角度测量值。该设备是完全手持式的,需要您同时握住工具和刀子,因此在阅读时要用两只手。我们确实希望他们集成了一种无需动手就能稳定刀的装置,这可能会使读数更加准确。

The Laser Knife Edge Reader is a simple but clever design that uses a laser pointer to beam light onto your knife, which will then reflect light towards an angle scale in front of it. You take the reading on the left side, take the reading on the right side, and add them up to get your knife edge’s angle measurement. The device is completely handheld, requiring you to hold both the tool and the knife at the same time, so you’re taking up both hands when doing a reading. We do wish they integrated a facility to steady the knife hands-free, which would probably make for a more accurate reading.

将刀插入工具时,需要确保将其正确放置在激光路径中,并且厚边朝向激光。光线将沿着刀的侧面向下传播,使反射的光弯曲到刀刃的一面。这意味着,一把锋利的刀将在两侧产生干净、弯曲的反射,而钝的(或锋利的刀)将产生模糊的反射。如果您可以确保将刀完全稳定地保持在激光的正下方,它也可以精确地测量双斜角。

When inserting the knife into the tool, you need to make sure to put it right in the path of the laser with the thick edge facing the laser. The idea is the light will run down the sides of the knife, bending the reflected light to the way the knife tapers. This means, a well-sharpened knife should will make clean, curved reflections on both sides, while a dull (or badly-sharpened one) will make a fuzzy reflection. It can also measure double bevels accurately, provided you can make sure you’re holding the knife completely steady, straight down the middle of the laser.

激光刀刃读取器是理想的测量工具吗? 除了不能使手保持稳定的人可能会感到困难之外,您还必须分别握住工具和刀的事实也非常麻烦。据我们所知,要找到像这样的消费级工具并不容易,因为任何具有类似功能的设备通常都是针对商业用户的,这意味着它们很昂贵,这使得它成为普通用户的最佳选择。

Is the Laser Knife Edge Reader the ideal measuring tool? Hardly. The fact that you’ll have to hold both the tool and the knife separately is quite cumbersome, apart from likely being difficult for those who can’t keep their hands steady. From what we can tell, it’s not easy to find a consumer-grade tool like it, with any equipment performing similar function usually being aimed at commercial users. That means, they’re expensive, making this the likely best option for regular users.

上半年,该测量工具的3D打印版本已经在亚马逊上售卖,尽管新版本具有笨拙的构造和第三方激光指示器,但它的功能几乎与新工具相同。不过,该新版本将使用在工厂生产的注塑成型零件,因此除了具有更好的激光笔外,它还应该具有更好的构造。另外,批量生产应该会使其便宜得多。

A 3D-printed version of the measuring tool has been available in Amazon for the last half of the year, which does, pretty much, the same things the new tool does, albeit with a clunky build and a third-party laser pointer included. This new version, though, will be factory-produced using injection-molded parts, so it should have a much better build, apart from having a better laser pointer. Plus, the volume manufacturing should make it much cheaper.

目前 Laser Knife Edge Reader 在 Kickstarter 众筹中。如果您不能等待众筹版本,也可以进入 Amazon 获取3D打印版本。

A Kickstarter campaign is currently running for the Laser Knife Edge Reader. You can reserve a unit for pledges starting at $40. If you can’t wait for the crowdfunded version, you can also use the Amazon link below for the 3D-printed variant.
