Thread: Video: Making of Dovo Straight Razors

This video is from one of those endless "Science&Nature" TV shows here on German television, so I don't believe this is some sort of marketing ploy for comissioners

I know too little about working metal, so I cannot comment on the credibility of this "straightening" process. On the other hand I believe this video to be directly from the production lines, therefore I think that Dovo must think that it makes sense to do this step

In the spoken text the argue that the hardening procedure leads to some very very slight warpage that needs to be corrected.

Well, just my 2 cents,

I believe that is the video DOVO also shows to their comissioners, and it's the " there is no warpage at the blade, here's our guy correcting it" part... Now, maybe this is for the TV, and after the razors have been baked, but

It looked like a bigger hammer was used for straightening to me.

Yeah, that straightening part was confusing me as well.
I think you would have a hard time straightening it with those tiny hammer blows to begin with, but after the lead hardening ? It should be even harder then, and the steel would be brittle, too, so I wouldn't necessarily want to hit it too hard.
Then again, we're talking about a guy who only needs 2 minutes for a hard-boiled egg - anything is possible then.

Thanks for the post Axel. I could follow the video but not the German (It has been lost in this second generation of German ancestry here). I feel a kinship with things technical and precise so the method of production and end result are important to me.
