掰到90度,让我满足的不行,再反方向居然那么容易就断了。谁给解释下,我的意见是多次掰出了金属疲劳。
看了回复,无比痛楚,补充一些:
ABS锻造算是碳钢刀的顶级要求了吧。我们来看看ABS MS大师刀匠的测试要求:
Test Knife Specifications:
Overall Length of Knife: Maximum fifteen (15) inches. 全长不超过15寸,就是38公分
Blade Width: Maximum two (2) inches. 刃宽不超过2寸,就是5公分
Blade Length: Maximum ten (10) inches from point to the beginning of either the guard,
bolster, or handle of the blade.刃长不超过10寸,就是25.4公分
对于ABS MS的锻造碳钢韧性要求:
BENDING: THE PURPOSE OF THIS TEST IS TO SHOW THAT THE APPLICANT IS ABLE TO HEAT
TREAT A KNIFE WITH A SOFT BACK AND A HARD EDGE.
The bending of the blade is the final test. Safety gear should be worn. The edge and point
will be dulled prior to bending. The Master Smith will mark a line across the width of the blade
approximately three (3) inches from the tip of the blade. The blade will then be inserted into
Page 4 of 6
a vise, tip first, such that the blade is placed into the vise up to the mark on the blade. If the
vise jaws are very rough, smooth metal or hardwood inserts may be placed on each side of
the clamped portion of the blade to protect it when bending the test knife. The blade shall
be bent by force applied to the handle. A leverage device, such as a pipe may be used as
long as it does not pose a safety risk. The use of such a device is at the sole risk of the
applicant and at the discretion of the supervising Master Smith. The applicant will then bend
the blade ninety (90) degrees.
ABS 测试要求刀扳成90度,刀刃不允许有超过1/3宽度的裂缝,ABS考试也没要求无损。
对于视频中的Mora,前期掰弯的时候,没有90度也有80度,刀刃未见异常,且是多次。ABS考试并没有这个多次的要求。
还需考虑到这个80度折弯是发身在仅有3-4公分的刃长上。
多次掰弯以后,反向折弯断了,哇,烂货,哇不如阳江,谁给提供个能做同样测试的阳江?我花了2年时间在找可以为国争光的阳江。将不省感激。
abs考试更没有反向折弯的要求。
同样的硬度下,同样的测试,可以试试。
同样的视频,我看见的是Mora又一个神话,而有人看见的却是神话的破灭,我很无语。 |
