Chip on ha machi

[Stephen]

Ive ran across this several times I just wondered if it was the thing or just happen stance on all of them.

I have a few blades that have damage like that. As far as I am aware, when a sword strike occurs on the habaki, it bites into it and often damages the blade underneath it; then the habaki is typically replaced. Here is an example where the original habaki is kept and you can see the damage to the blade under it:

Slapping blade down hard on shirasaya or saya often the culprit. Super annoying and a serious put off to me on a blade.

These were not skilled swordsmen, which is why the burglars lost the fight. Jeremiah is right that Stephen's nick was likely caused by stupidly slapping the blade down.

Makes sense!

Have seen many, own a few. I'm guessing that edge is a weak point for sloppy habaki fit or handling.

I'm with Brian on this one. The Ha-Machi is a very sensitive place. A sloppily made and not correctly fitting habaki can quickly cause damage here.

Ok i understand the habaki as the culprit.,

When you say slamming down are you talking about putting it back in saya to hard?

[Brian]

I suspect dropping the blade downwards with the tsuka vertical.
