These are "Hazama" tsuba using the exotic sahari inlay (silver, lead, tin, etc mix- possibly using mercury in the process) that is incredibly hard and possibly toxic in the manufacturing process.
Ford said he could do it, but I would say it is one of the times where his bravado got ahead of him. His sahari inlay did not convince me at all. It looked very modern to my eyes.
Sahari was also used to inlay gun barrels, as it won't suffer from the heat.
Sometimes Hazama (and closely related Kunitomo) tsuba are referred to or known as "gun-maker" tsuba and enjoy a little panache in Japan for that reason.
The orange lighting from above doesn't help. Having seen at least 100 of these and owned 4 or 5, I can look past the odd lighting and properly imagine what they look like.
For Hazama, the designs are on the dramatic side. I'm not saying I'd want to own either, but the inlay and use of sahari on the Taiko drum Hazama is relatively impressive.
I doubt the ropes are sahari. They are probably another much softer metal, like silver.
Very unique tsuba, but I'd 100x more prefer to have the skull Nobuiye.
