The blade is tempered or hardened by putting it in molten lead, which seems to be the ideal way to harder. TI is the only one that does it because it's illegal in most countries, including France (TI seems to have a special dispensation).

Most of that is marketing hype, as DOVO also uses molten lead to temper their razors too...

Thanks. I just ordered a T-I to rotate with my Feather and was curious about the markings on the blade.

I can see that this isn't going to stop anytime soon.

Most of the markings as joe said, such as Eagle, are used for different vendors so not two vendors in the same sales are (USA) will have the same production razors. On special editions...damascus, etc....they will often use different handle materials so each dealer has something unique.

The more specialized names come from a list of trade names TI has used in the past and will often resurect them for a new dealer.

I wn 14 TI razors now from the least expensive to the most and love them all. Actually with the exception of a few very old meat choppers and one Filarmonica they are the only brand I own and use right now.

I don't think that's right. If you have some information that uses Dovo lead hardening, please identify it.

I believe they were doing it in the video of their production process but I'm not 100% sure as it was in German lol.

Why you don't think that's right? Just because DOVO didn't said so before? Check this discussion:

http://straightrazorpalace.com/showt...ght=DOVO+video

And also the DOVO video:

Click on "Schnell: DSL/LAN (min. 600kBit/s)" and then "> Speichern und zum Video"

In time mark 2:55 you can see the lead tempering process, while the narator talks about "the razors being covered with graphite, and then immersed in bath of molten lead. The graphite prevents the lead to be stuck to the metal. The bath temperature is more than 850 Centigrade."

cheers,

Thanks Nenad. I never saw that before. As rough as my German is now, I can tell you're right.

The reason I thought it wouldn't be done is because it's quite toxic and bad for the environment. The Germans are very tough about those kinds of things. The French, on the other hand ....

Thanks. It was very interesting.

You're welcome...

My German is rusty too, but I recognized the word "blei" (lead) from the sticker at the gas station (bleifrei=unleaded). I than payed more attention

cheers,
