家居生活Laser Knife Edge Reader 激光刀刃測量器,專測刀的鋒利度或鈍度

2020-01-02  2284

如果手頭上有適當的工具,則削鈍刀就很容易了。但是,每次將其始終保持為相同的水平是很難得事,因為要獲得客觀的邊緣銳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.

這是一種手持式工具,可讓您測量放置在刀片上的刀刃的角度,它為確定刀的鋒利度提供了客觀標準。這樣,如果您需要以能產生完美切割效果的方式銳化刀片,則可以對其進行測量,并在下次處理其邊緣時嘗試達到相同的角度。

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 是一種簡單但巧妙的設計,它使用激光指示器將光投射到您的刀上,然后將光反射到刀前的角度。您將讀數取到左側,將讀數取到右側,然后將它們加起來即可得到刀刃的角度測量值。該設備是完全手持式的,需要您同時握住工具和刀子,因此在閱讀時要用兩只手。我們確實希望他們集成了一種無需動手就能穩定刀的裝置,這可能會使讀數更加準確。

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.

將刀插入工具時,需要確保將其正確放置在激光路徑中,并且厚邊朝向激光。光線將沿著刀的側面向下傳播,使反射的光彎曲到刀刃的一面。這意味著,一把鋒利的刀將在兩側產生干凈、彎曲的反射,而鈍的(或鋒利的刀)將產生模糊的反射。如果您可以確保將刀完全穩定地保持在激光的正下方,它也可以精確地測量雙斜角。

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.

激光刀刃讀取器是理想的測量工具嗎? 除了不能使手保持穩定的人可能會感到困難之外,您還必須分別握住工具和刀的事實也非常麻煩。據我們所知,要找到像這樣的消費級工具并不容易,因為任何具有類似功能的設備通常都是針對商業用戶的,這意味著它們很昂貴,這使得它成為普通用戶的最佳選擇。

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,該測量工具的3D打印版本已經在亞馬遜上售賣,盡管新版本具有笨拙的構造和第三方激光指示器,但它的功能幾乎與新工具相同。不過,該新版本將使用在工廠生產的注塑成型零件,因此除了具有更好的激光筆外,它還應該具有更好的構造。另外,批量生產應該會使其便宜得多。

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 眾籌中。如果您不能等待眾籌版本,也可以進入 Amazon 獲取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.
