Kissaki size

[Justin]

I sometimes have trouble distinguishing between ko-kissaki and chu-kissaki.

 

Are there any specific definitions of ko-kissaki available (eg. width at the kissaki as a percentage of other measurements)?

Hi Justin,

 

I heard that if the distance from

 

the tip of the blade to the yokote

is longer than

the yokote itself

 

you speak about an O-Kissaki.

If it is of similar length it´s a Chu-Kissaki and if it´s shorter you have a Ko-Kissaki.

That´s at leat what I heard so far. Hope this helps.

 

Cheers,

Martin

I am sorry, but I cannot agree with the theory.

If the kissaki is Ko-kissaki, Chu-kissaki, O-kissaki, or even Ikubi-kissaki, generally the distance from the tip to yokote of each type of kissaki is always longer than its yokote.

Hi,

 

sorry

I meant the proportion between the yokote-length and the ko-shinogi-length.

Correct me if I´m still wrong

 

Cheers,

Hi,

 

I understand the theory.

However, I think that the difference between ko-kissaki and chu-kissaki is not the local proportion of the kissaki. IMHO, the difference may be identified from whole proportion of the blade.

 

On the picture below, upper right shows ko-kissaki and upper left shows chu-kissaki.

Thanks very much for your responses.

 

I appreciate your assistance.

 

Moriyama-san, I understand what you're saying about looking at the shape of the blade and making a judgement, however I sometimes stll have trouble with ko-kissaki.

 

In your diagram I can clearly see that the image at the top left is chu-kissaki, however to me the top right image could be also be chu-kissaki as the blade width seems less than the top left image. That is why I am looking for a rough definition to help pick the difference.

 

I apologise in advance if this seems like a novice question.

Hi Justin,

 

Actually, that is the point. As for ko-kissaki blade, because the blade width near its tip is narrow, the kissaki has to be small naturally. As a result, that becomes ko-kissaki.

 

This is only my understanding. I am also a beginner.

Hi Koichi,

 

you are right - I checked a few online ressources and they all say that the whole proportion of the blade is decisive.

Also looking at some pictures make evident that the theory I mentioned above doesn´t seem to be (always) correct and therefore can´t be a rule.

The following Link underlines your statements and sums it all up.

Hi Martin,

 

Thanks for the info. I did not know the page, though I have seen the home of the site before.

[Justin]

That clears it up.

 

Thank you Martin and Koichi-san for your comments.

 

I have been a member of the NCJSC for some time now, but haven't seen that page on the website - thanks for pointing it out Martin.

 

Best regards

Justin
