Well, for me, it's a file worked back on the blade. That simply bespeaks an extra effort on the part of the maker. Jimps on both sides of the tang and an added plus is a curved tang with double jimps.
An engraved, not etched, blade, ala "Carbo Magnetic" also shows more craftsmanship. Someone once said that a "roll engraving" process was used on the Carbo Magnetic razors.

For handle material I prefer natural materials over the plastics. But, a set of transparent scales has a unique appeal for me as long as there are a set of decorative bolsters on the end.

The black and gold etching on a blade, ala Puma, is quite attractive.

A square point is preferred over a round point any day. A round point simply is not threatening.
I just did some restoration on a razor that was in really bad shape shape. I got it for a $1.
It is a Boker, now 45/64ths, so I thought it would be worth the effort. Lots of rust, pitting and the tip was broken. Well, for the tip I ground it down on a 3 inch wheel and just followed the curvature of that wheel. Talk about a spike point! Whoa!

Off to honing land,
