Thread: Stainless steel razors on Shapton Pros.

I don't like the smile, and it's simply too much... And most importantly I don't like the ground. I most likely have reduced the lifespan by 5 year, maybe 10 years, silly isn't it?

Probably why it won't hone up, now. U ruined the geometry.

I'm pretty sure the geometry is right, I know what I'm doing. The edge is still popping my finest hair on my hand easily but not as good as I would expect it to be. It looks like the Shapton Pro 30K cannot handle the hard stainless steel(Titan claimed it to be HRC 70, I would say even if it's not 70, it would still be in the high 60s, it skids a bit even on diamond plates) as I see much less swarfs than carbon steels.

I suspect if I strop on 0.1micron diamonds, I can bring it up with more or less 10 strokes. Have to pull out the strop though, haven't use it for quite a while.

I think you have that backwards. Not all steels can go s fine as 30K grit. Also geometry aside, as you go up into the very high grits one can thin the edge down very fine and it becomes very fragile.

I think you might be right, it's either the razor could handle it or the stone could not cut the stainless steel efficiently. So I've pulled out the Proyan 15k and did 20 laps on it and tried to shave, it was not as keen as my other razors off the Shapton 30K, but I have to say it was a comfortable one.

The Shapton 30K glass is a polisher. I have to have a pretty much finished edge to notice any improvement from it. I find that my coticules can put a really nice edge on even the hardest steel and then if I go to a Vermio or Pierre la Lune it gets better. There is no question the bevel gets its best polish from the Shapton, but quite frankly, I don’t notice any improvement in the shave I get from the other finishers.

Titan Razors can't handle that edge they barely shave

To be honest most razors can't handle a 30k edge, Want to see what it is really capable of find a NY made double hollow preferably made in the Little Valley area
They are cheap and easy to find, the steel and temper can show you what a real 30k edge is

There are other singular razors that can hold that type of edge but not brands or areas like the Little Valley area brands they are your best bet of getting one that will match that hone

I think my Dovos and Boker can actually handle that but only 5 to 7 strokes, no more. It can be over done so easily that I tried with 10 laps on the first go and the edge was full of micro chips just after ~10 shaves.

Could you please share maybe one or two examples? There ain't many stores selling straight razors in Australia, I'm not even aware of any physical stores at all. So currently I'm playing a hit or miss game.

Yeah your not going to find one in a store
No your Dovo and Boker are not nearly as good off a 30k as the fine grained steel found in Vintage NY razors

Look for brands like

Kinfolks
Cattaraugus
Thistle
Olean
Genco / Geneva

Look for the NY stamps, this isn't hard and they are often quite cheap on the used markets

Not sure where you got the idea of 5-7 strokes on a 30K besides on my vids, keep in mind that is after a proper set up on the full grit ladder

YUou mighty also try what we call a Micro-Bevel after the 15 or 16k
