Check out this Yoroi-doshi

[Blazeaglory]

This is what outlaw bikers call a "sharp finger". Not pretty but very effective!

 

I've seen quite a few Yoroi-doshi but this one scares me for some reason. With only a 7" nagasa, it looks like it could really ruin a persons day...

Looks more like a spike.

Exactly. Like a Fallout 4 apocalypse rudimentary sharpened railroad spike lol

Mmmmmmm (brickbat shield up), I would opine its not an armour piercer because it has the wrong shape.  An armour piercer needs to be blunt, like armour-piercing arrowheads, unless one uses the argument that such a shape is used for slipping under the armour scales, in which case it might called an armour slider??!!  However, it does look like an armour piercer that has had Satsuma age done on it.

 

BaZZa.

Yoroi-doshi were usually used as spikes, Get the point into the armor, & then bash the kashira with the palm of the hand. My Sensei showed just how much force that gave by driving his blade completely through a 3" piece of bamboo. He's 83, so it didn't take a lot of bashing.

That's what I was thinking too. Reminds me of that knife smith who makes modern tantos then shows the durability by punching them through car doors and steel drums

Very awesome Ray, I never knew these type of Yoroi-doshi existed. They seem purpose built for quick death

Wow. That’s got to be pre-edo jidai. Truly a purpose built tool, meant for the battlefield.

Looks to be close to the European type of  medieval dagger with triangular blade section, called 'Gnadgott' in German or Misericordia in Italian.
