looked into diamond coats, nitride coats, titanium razors etc.. Honing is the issue. the blades will eventually blunt, and when they do, honing will be difficult. It is forseeable that you could manufacture a diamond of the right size/shape as a straight razor and I doubt you'd need to ever sharpen that, but cost? not sure, plus it wouldn't have any flex.
How's the steel in these razors? I'm pretty sure the titanium is just a coating for the overall price of the razor. Does anybody know who makes the steel/where it comes from?
I fear the edge of such a razor might chip very easily. Diamond is very hard, but also very brittle. A big issue with an extremely fine razor edge.Quote:

If its titanium nitride, all it is , is a ceramic coating. Short of being familiar with industrial tooling,most people see it on drill bits. Its REALLY hard-something like 85 Rockwell. Which would be a true B&^%H to hone.
Then since it would be practically impossible to make the coating PERFECTLY uniform, you would wear through some and still have coating on what's left of the edge-then the hone would wear the edge unevenly.
It really does'nt work on drill bits-other than for non-professional use.The coating wears off,almost immediately . Most very high end drills are made from a steel alloy containing COBALT. It seems they are trying to reinvent the wheel. Most custom razor makers have a very good working knowledge of metallurgy and manipulate the materials molecular structure to make a more durable edge.
There are already very fine steels, some found on even on vintage ebay specials. IMO, its just another marketing ploy to sell a product that really isn't needed.:shrug:
Indeed.Quote:

It really depends much on the razor how far you can push a razor in the sharpness envelope. I believe a diamond cutting edge would hit that barrier of brittleness sooner than a steel one would. Razor makers choose their hardening and tempering parameters with great care. They DON'T want the hardest possible steel, for reasons stated above. With diamond, one cannot influence the hardness/sturdiness ratio.
But wait, I have a better idea. Why not attach a bunch of small stainless blades to a circular plate, and connect that to the shaft of a small electro motor. Such device would make shaving that much easier. You just plug it in every morning and shave away. Technology rules! (I believe I'm going to start checking for a patent right away) :D

I don't think i like that idea....i like to keep atleast a LITTLE bit of skin on my face:HJQuote:

I bought a Venus razor when I first started straight shaving, I'm embarrassed to say. To be blunt, they are Paki made pieces of crap! The thing would not hold an edge. I ended up giving it away. Buy one at your own risk.
I think we all need to remember that all of the commercial sources for new razors are all well known and documented. When someone comes out with a new brand no one ever heard of before I think it prudent to assume its either Pakistani or Chinese or comes from some other place you would not want to be getting a razor from.
Yep, agree it seems a very rare occasion this happens. But there is a precedent... Wapis! :tuQuote:

Venus has been around for awhile. It was almost six years ago when I bought one of their razors, before I found the SRP, but I doubt the quality has improved.
This is very true IME as a welder/machinest the best tool's for an experienced hand are cobalt, and the reason i say experienced is they DO NOT like to flex. If you use one and flex the bit its going to shatter wich is why super hard materials arent good for razors. Yes hair is small and easy to cut but the fine edge of a razor is equally small and if it cant flex even infantesmaly it will break, remember that all things that dont bend break. On the same turn you dont want the edge basicly moving out of the way of the hair. Wich im guessing is why the stated razor while sharp wont cut. The metal is to maliable and just dances around the hair. i may not be an experienced bladesmith but as a third gen, metal worker i know metal like most people know there kids lolQuote:

Obviously it would not be suitable to shaving but diamond blades can be made very thin and remain functional for specific purposes. Also from what I've read the blades are quite expensive, as in representing a significant portion of the operator of the scanning electron microscope annual pay, and each technician usually owns their own.Quote:

I've made this observation on every one of these Venus Titanium threads that I have encountered but I guess I missed this one. For the sake of anyone who might consider buying one of these, consider the following.
This thing defies all logic. They declare that the blue titanium coating makes the edge sharper and stronger. Well, look at the EDGE. Do you see any blue there? The only place the coating might matter is the one place where it ain't. I could go on, and I have in other threads, but just read the description of the razor. They declare that the coating is not removed by honing. Well if that were true, then it would be impossible to sharpen, since sharpening involves steel removal, but clearly this is not true because the coating is not at the edge! Do you see any logic in that?
Now that is worth knowing, and it doesn't surprise me.Quote:

I don't think it is likely to be possible to firmly bond it to steel, either. I'm sure what Venus has is a titanium nitride coated razor.
This is immensely hard, but quite brittle, and therefore not likely to be much better than the steel under it. A razor edge does bend this way and that, and needs to be straightened up by stropping. Steel can indeed be chipped, on a microscopic scale, by hair. A very sharp hunting knife undoubtedly would, if you hacked a substantial chunk of horn with it, and hair is made of keratin too. You would need a synthetic hone or diamond lap for initial and perhaps every honing.
Of course if you were making a razor out of miserably bad steel, the priorities might change.
As it should be, so it shall be.Quote:
