关于凸磨 --英文版（熟悉英文的翻一下-有加分）

There is nothing New about Convex Grinds or Convex Edges.

All Knives-Swords-Axes and Cutting Tools have been Convex Ground and
Sharpened from the Bronze Age to about 1900. The Advent of Automated
Grinding during the Industrial Revolution saw the first V-Bevel methods of
Sharpening knives. This was necessary because there are no machines--even
today--that can do a proper Convex Grind or Convex Edge.

Convex Grinds and Edges are all Hand Done.

The Advantage of the Convex Edge is that it supports the Carbides on the
Cutting Edge by an almost 400% advantage to the -now common- V Bevel.

Convex Edges hold thier level of sharpness far longer than a V bevel and are
4 times tougher. They are also deceptivly sharp.

The Thick Edge Spine holds the carbides on the edge to such a longer degree
that the knife stays sharper far longer and will still cut long after a
conventional V bevel has gone stone dull.

Convex Edges are also the Easiest to Maintain and restore.

A quick strop and they are right back to Razor Sharpness.

All of the Classic Series of Blackjack Knives are Hand Convex and Hand
Sharpened in the Traditional Manner to give you the Ultimate in cutting
performance without compromising strength and toughness.


如何恢复锋利

KEEPING YOUR BLACKJACK EDGE

DON'T use a stone. Stones make flat places and your edge is convex. Just stroke the edge --- only the edge --- backwards on cardboard, leather, crocus cloth or any other MILD abrasive every few days and that is it. Yes --- just lay the knife flat, lift the back of the blade until just the edge touches the su**ce, and pull it firmly backwards, with down pressure, stroking the whole length of the edge. Repeat on the other side. Stroke point-to-handle OR handle-to-point, whichever works for you.

Edge gets flats or nicks? Easy. Get wet-or-dry sand** in 320, 600 and 1200-grit, lay it on a mouse pad or other yielding su**ce. Stroke your blade backwards in the same stropping mode, first on 320 grit, then 600, then 1200, and repeat as necessary to eliminate the damage. Finish on cardboard (or leather, etc.) and you will have your beautiful convex edge back.

凸磨没啥稀奇的

All Knives-Swords-Axes and Cutting Tools have been Convex Ground and
Sharpened from the Bronze Age to about 1900. The Advent of Automated
Grinding during the Industrial Revolution saw the first V-Bevel methods of
Sharpening knives. This was necessary because there are no machines--even

从青铜时代到大约1900年期间，所有的刀剑斧头和切割用具都是用凸式打磨法打磨锋利的。直到工业GM时期，自动化打磨方式才造就了第一批采用V面打磨法打磨的刀具，究其原因，是因为直到目前为止，都没有机器能够进行凸磨。

Convex Grinds and Edges are all Hand Done.
所有的凸式打磨都是手工进行的。

The Advantage of the Convex Edge is that it supports the Carbides on the
Cutting Edge by an almost 400% advantage to the -now common- V Bevel.
凸式打磨的好处是刃部的碳化物所受到的支撑力是现有V磨的大约4倍。

Convex Edges hold thier level of sharpness far longer than a V bevel and are
4 times tougher. They are also deceptively sharp.
凸磨出来的刃部的保持性要比V磨的好得多，强度是V磨刃部的4倍而且非常非常的锋利。

The Thick Edge Spine holds the carbides on the edge to such a longer degree
that the knife stays sharper far longer and will still cut long after a
conventional V bevel has gone stone dull.
那厚重的刃部脊线可以是让刃部的碳化物更加的稳固，所有凸磨法打磨的刀具可以长久的保持锋利，在使用很久之后还可以顺利的进行切割作业，而相对的V磨刀具可能早就钝到无法使用了。

Convex Edges are also the Easiest to Maintain and restore.
凸磨法打磨的刃部也是最好保养和复原的

A quick strop and they are right back to Razor Sharpness.
稍微用皮带蹭蹭，立马又可以变得像剃刀般锋利。

All of the Classic Series of Blackjack Knives are Hand Convex and Hand
Sharpened in the Traditional Manner to give you the Ultimate in cutting
performance without compromising strength and toughness.
所有的黑杰克经典款刀具都是用传统方式手工凸磨，能赋予你无上的切割性能，且不会对其强度和韧性造成影响。

不要用油石打磨，因为油石磨出来的地方是平的，而你的刃部是弧形的。你只需要把刀刃 - 记住只是刀刃 - 在纸板，皮子，粗袋布或其他比较粗糙的材料上每天蹭几下就行了。很简单-把刀放平，然后把刀背抬起直到刃部与表面接触，然后用力的将刀向后拉并同时向下施力，将整个刃部都蹭到。另一边也这样。方向可以使刀尖到刀柄或者刀柄到刀尖，随你喜欢。

Edge gets flats or nicks? Easy. Get wet-or-dry sand** in 320, 600 and 1200-grit, lay it on a mouse pad or other yielding su**ce.

刃部变平或者崩了？也简单，找点320,600和1200号的砂纸，放在鼠标垫或其他可以弯曲的表面上，使用相同的研磨方式逆向对刃部进行研磨，先用320，再用600，最后1200，直到损伤被消除为止。然后在纸板或者皮上对刃部进行收面处理，这样你那漂亮的凸磨刃部就会再次出现了。

2# 石中火2046 牛人~~这么快就翻译出来了~我要学学凸磨，谁能讲讲，详细的……

我前段时间买了一把小直刀，刀刃非常锋利，就是凸磨刃口，用手指头肚沿刀刃轻轻划过 感到很光滑，不用力是不会划破指头的，但以前油石研磨的刀，这样滑过就不光滑了，且很容易划破手指，这种就应该是通常所说的v磨，虽说当时锋利但保持性太差。但悲剧的是我吹毛求疵找到刃口一点有点发白，我想修补打磨一下那个点，但油石怎么也磨不到那种凸磨光滑的程度，知道今天看帖才知道油石不能打磨凸磨刃口。以至于基本把整个刀刃都磨的乱七八糟，有个地方磨左边右边就卷过去，再磨这边那边又卷，当然是很小的了，用手指可以轻微的感觉到~
但我想知道的是这种凸磨最开始磨刀师傅是怎么磨出来的，我该怎么才能磨出来凸磨，现在我刀差不多快变成v型刃口了~

胖如熊

剪张金相砂纸 一块橡胶垫 软的象橡胶的鼠标垫也行开磨吧

好文！很喜欢FallKniven的凸磨，确实如文中所说锋利、保持性好

不软的，是磨刀水平差，刃口那里很薄，不小心就会磨过去的，卷刃也是很轻微的，~

meilanyu

其实磨刀分两步 一时修刃 一时磨光滑。
用的没有豁口就不用修 感觉钝了磨下就成。

当然磨光滑的過程 磨的时间长了 也能起到修刃的功能。

所以FK的刀最好配皮鞘？哈哈，不错。

下面第一張照片，是刀子原廠的V形開鋒，我拿去砍鐵輕微受損後，就在一疊紙張上面，用1500號的細砂紙磨刀刃，可以看得出來明顯的差別吧！由於是便宜的刀子，所以隨便磨一磨，連拋光膏都不用了

meilanyu

这个很直观，磨的还是很漂亮的。

这原厂刃和新改刃 用起来啥区别的？

万雷束一刃

这个要看看 F1有点炖了

凸磨就是蛤刃？

丈八两头蛇

我是这样搞的：
200#-1500#用油石，慢慢来，因为手不稳，自己会在一个范围内晃动，所以打出来直接是凸磨。
然后把高一点目数的砂纸裁成1-2cm宽的小条夹在桌子上，另一边用左手拿住，保持一定的张力，那刀子在上面荡。确实蛮方便的，op用坏掉也是这么捣成凸磨的。
