A couple of thoughts:
1, Regarding handle tightening.
Tatara has designed the interface between the handle, base plate and top cap different from any other razor known by me and in accordance with sound mechanical engineering principles.
From a layman's perspective. Properly, any interface should be done in double shear separating the fastener from the pieces being held together effectively separating clamping from torquing forces. This technically is impractical in this application so
Tatara has the handle completely embedded within the baseplate to provide extra strength to the otherwise weak interface. For example many top cap threaded fasteners break at this junction because it creates a stress riser that fails when impacted, say from dropping. The
Tatara interface will take a much higher impact without failing as the interface is reinforced with another layer of metal and the stress rising threads not exposed.

2, Regarding the finish.
Tatara is a highly and consistently branded product. Their brand is centered on samurai lore from swordsmiths to great swords. Note their logo.
The greatest of all Japanese swordsmiths was Masamune. To this day a prize is awarded for the most advanced and perfect of swords produced on an annual basis. So prestigious is the award, that if no sword meets the highest standard, the award is retained until the year when it deserved - a major point of divergence between Western standards of adequacy and Eastern standards of excellence.
Masamune's swords had a unique nie finish that was flat and sparkled next to light.
Tatara has captured that nie finish as a signature branding element. It, in fact, is expensive to create so not as though it semifinished.

Should you prefer to remove this unique design element making a

Hope this helps address your concerns.
