Meat slicing knives that probably we will never get them again.

They are probably 240mm blade and 300mm blade (sorry I have not measured them yet).
They were made as steak knife (slicing meat and tap on the bump on the spine to make the meat softer.
One of the knife was placed the order decades ago to the cutlery store in Japan, so the owner of the store had placed the order a couple of more pieces in case of the chef might place the order another.

The knife looks like weapon, so the owner of the store scares to sell it in Japan. It might be indicted by law in Japan, so I am so lucky to get them.

It was made skillful blacksmith who made it from the single piece steel from the blade, and the hilt, and tang. No welding the bolster.  Classic style.  I was told it was water quench blade.  The handle looks like Makassar ebony. The owner of the store told me that they are very expensive at the time.

The blacksmith is gone, so we cannot place the order again.
