I've been experimenting lately with using alternate grinds to check for performance differences and have come to an odd conclusion about grinds and my face. It seems that the more hollow a grind is the worse the shave I get is. I recently removed my goatee and discovered that, that spot of my face simply jams anything smaller then a 6/8 going WTG. So I got a pro honed dovo best quality 6/8 and found that while it jammed less then my other razors it was still jamming up a bit. The only razors I own that seem to get the job done comfortably are my Wade and Butcher 5/8 wedge and my 45mm Iwasaki Kamisori. One piece of great news for me is my pro honed dovo isn't all that much sharper then my own honing work at home. I know what I'm shooting for now and I'm really not far off.
While I've noticed the more hollow grinds shave much closer then my wedge they just don't have the heft to get through my chin hair and given how light weight my kamisori is I'm starting to think grind is the real determining factor. I think my next move is to try out some 1/2 hollow grinds and maybe 1/4 hollow grinds keeping it in the 6/8 range.
If any of you fine gents with thick tough chin hair have hit a sweet spot I'd love to hear about it! Also while I'm working on getting my house ready for a meet up I now have a bunch of razors that need new homes; I'm thinking of either using the classifieds or letting some of you guys see them in person. After removing my goatee all my 5/8 and smaller razors just aren't up to snuff anymore.
