Very Cool! :thumbup:

AFAIK, that is the first waki we've seen that displays the temper line.

How do you do your blast process?
 
That is AWESOME:cool:
Love the temper line:thumbup:
 
i'm confused. what does "double cut" mean? i see the temper line or hamon, is "double cut" just another term for differentially tempered? i was wondering why i couldn't see the hamon on the "satin waki", it's really cool to see it here.

also, what is that other skwiggly line? the one that starts at the handle and goes up about 3"? the one you can see really well in pic #4.

it's Beautiful, makes me less afraid of the coating wearing off of mine.

Double cut is just another term for bead blast finish, it involves 2 different mediums (hence the Double I think) aluminum oxide and glass bead, the AO turns the metal a dark grey and very rough to the touch then the glass bead polishes it to a no reflective surface. as to why the temper line doesn't show on satin, I don't know, might be because its a very subtle temper line and the satin finish over powers it.

And as for that other line, I have no idea, its a line of tiny triangles and was there before I did anything to the blade other than strip the coating with a chemical stripper and hand sand the grey undercoat off, its a mystery, I need to get Eric to take a look. doesn't really bother me though

I used an old sand pot and compressor I had around from work and used 100 grit aluminum oxide and 100-170 mil spec glass bead for the final cut
 
heres a pic of the temper line catching the sun, this was right after I finished it (hence the tape on the handle)

Looks like the CNC bit danced on it during production.:D
Combat grade knives aren't finished as well and you don't ever know exactly what's under that coating!

Bussekin steel is usually pretty fugly under the paint. I have seen that ugly squiggle on blades that I have stripped. You never know how bad the nekkid steel might be until you strip it. Sometimes it can take a lot of grinding to remove all the marks like that, or, on INFI, the ugly pits.

thank you for the explanation :)
 
Interesting. I was expecting the temper line to be more uniform as they tend to be on some of the older rats. It looks like it was an actual mud paint procedure.

I was surprised as well that it wasn't uniform. I love the way it is but I was expecting it to be uniform
 
i wanted to DC one on mine but i was told that the SR101 would rust like crazy...how is it holding up?
 
I must admit, that really does look like a temper line. I don't know that I've ever seen an irregular temper line on a production piece. It almost looks as if the clay or whatever Jerry uses for insulation in tempering is hand-applied. Does anyone know what their process is?

it looks like you covered the scales.... would the D/C process mess up the G10??

No, I covered them as a precaution, during the blasting the tape got chewed up and I still had to get close to the handles to finish it out. No damage at all to the G 10, now I know for next time.
