Which 'ricasso' style is easier to grind?

[MichaelC]

I'm calling it the 'ricasso' but I'm not sure if that's an accurate name for what I'm talking about... I'm meaning the line where the grind ends opposite to the cutting edge. Most factory razors are ground to the spine or pretty close to it, but some custom razors stop further down. I know this is done to give more width to the blade and essentially make a larger razor from a certain thickness of steel (the reason I'm partial to it..) but so I just wanted to find out from knife/razor makers if either is easier than the other? Is using the spine as a guide for straightness of the grind more effective if grinding to the edge of the spine, or can scoring a line away from the spine be used in the same way..??

As mentioned, I have a set steel thickness, and would like to create a larger overall blade by moving the 'ricasso' down from the spine (obviously bearing in mind the correct ratio to attain proper honing angle - done my homework there...)

See attached image A - ground to the spine, and B thicker 'ricasso'.

Thanks guys for any insights/suggestions.

Cheers,
