Kurdistan dagger

ALEX · 8th May 2008, 07:20 PM

... few more pictures of Kurdish-style daggers (they also can be Persian or Turkish as well !?). All blades are over 10 inches long, and all are wootz (note the lighter quench areas near the hilts). One blade, in the middle, has a spectacular ladder Kirk Narduban pattern.

Do you hear that strange sound? That's me banging my head against my key board

Alex, this looks amazing. What are your secrets when polishing and etching a blade? How do you polish - very fine sandpaper, or something else? And what do you use for the etch? I would love to get a few tips from you (or the whole manual), as I have a Syrian dagger which exhibits a low-contrast pattern that I would emphasize a little more. Also, when you have a blade in a not so good shape, with heavy patina and pot marks, is there any way to coax a pattern out? I have a damascus yataghan, which exhibits four rows of Turkish ribbon on a small part of the blade, but I have failed miserably in my attempts to reveal the pattern on the rest of the blade.
Thanks,
Teodor

Teodor,
What I've learned is that good quality wootz requires minimum effort to be brought up nicely. Wootz blades which were not polished, grinded and buffed too much during their lifetime have tendency for better contrast when etched. Just like the examples shown above - these blades were in excellent condition, not just well preserved, but not "touched" much. They required almost no mechanical work. All I did was polished them gently with the polishing paste until the surface became mirror-like/shiny, then cleaned it with alcohol and etched with FerroChloride (FeCl) solution. I've worked with good wootz blades with heavy pitting, and when test-etched they were showing good pattern, but when grinded and polished to get rid of pitting - the pattern often lost its contrast and became distorted. I'd strongly recomment NOT to overgrind and overpolish wootz. The goal is to make an entire surface mirror-like without taking too much metal off and without overheating the blade - the less mechanical intrusion - the better! You can use very fine sandpaper with water, then sandpaper with oil, followed by dry sandpaper and buffing, and once the surface looks mirror-like -- stop!
Now, when wootz is low-contrast (especially Turkish or Syrian sham type) - this is how it meant to be by design, and there is not much one can do to increase the contrast, except of trying different etching methods - FeCl, acid, etc. and if it happens to be sham (low contrast wootz) - it'd stay this way:-) Finally, a wootz blade can have areas of pattern loss - different reasons - overheating, overpolishing, underheating:-) Good wootz will always show it's best with almost any etchant, and this is the secret:-) Hope it helps.

I think this is Turkish dagger, however it has some strong Kurdish influence - but the blade has no central ridge. I post it to demonstrate the pattern, which also required no work - just very light cleaning and slight FeCl etch - took 10 minutes.

Alex,
Thank you very much. There is plenty of good advice in your post. Here is the blade in question - I guess it is obvious it will never have a particularly strong contrast, but for some reason I think there is some room for improvement. You can barely see the pattern, but it is there. I did degrease the blade with alcohol and then I soaked it into diluted vinegar for about 12 hours (I tried a few hours only and had no result, so I left it in longer).
What is your opinion, should I try another etch, or this is as good as it will get? I have not polished the blade with anything, I only removed rust months ago with brass brush manually (no power tools).
Thank you,
Teodor
