Hello chaps,

I'm one of those guys who is blessed with cast iron bristles.

My aim is to get that razor that makes me feel that it's cutting through my duras barbes like a hot knife through butter and still make my face think it's being kissed by angels.

As a follow-on to the 5/8" or 6/8" thread, I would like some seasoned, experienced opinions on the which blades cut tough bristles best.

From what I have read, heavier razors are thought to be better, possibly due to their higher mass. And hollower grinds are more comfortable because they flex ever so slightly.

The mass of the blade can be increased by either increasing the width of the blade or using a thicker grind. Or both.
But, wide blades are apparently difficult to use, and the shavers of old seemed to favour the 5/8". Then again, I guess the average person has relatively soft bristles, so the average vintage razor size should reflect this.
On the other hand, the thicker the grind, the less comfort inducing flex in the blade. Wedge grinds are also more rare than full hollow grinds. Is this also due to the law of average beard hardness ?

To sum it up;

Is it true that heavy blades cut effortlessly or is it just a matter of how you use it ?

Is there a sweet spot ? Small wedge or large full hollow ? High carbon steel or stainless ?

Or do I simply need to learn to use my 5/8" singing razor properly ?

I look forward to your informed opinions and personal preferences.

Thanks,
Ian.
