I have noticed that some new razors come with some visible spine wear from the factory, such as Dovos for instance, and others with no visible hone wear, such as Thiers Issard.

I have also noticed that most vintage NOS razors have no visible hone wear.

Does this mean that some razors are honed flat on the hone and others are honed raised?

Or is the spine wear buffed out after honing?

If in fact some new razors are honed raised to avoid visible hone wear then does this not goes against the frequently read theory that the razor is designed to have its spine and bevel wear simultaneously, hence, without tape ?
