there is some pitting on my blem, can someone concisely walk me through the repair and refinish process including grit #s and compound names, etc..?
thanks
 
hey, man, that's part of the villager/blem chic! ;)

some of what you see as pitting is probably jsut an area where some of the forge scale was removed but the surface steel wasn't totally ground and buffed down. I wish I could get one with pitting all over!

Hmmm...sounds to me like ya need someone to etch a pattern on there that hides the imperfections...:)

Danny, I need to do a search on that myself. There's a very small dark spot on my new UBE. Tell you the truth though, it doesn't bother me and I probably wont touch it even after I read the results of your thread through.

My UBE had some spotting after I used it on a humid day and didn't have time to clean it- so I used scotch brite and followed the wave of the blade. Now it looks like a 1000 grit hand rubbed finish. I like it. :)
 
Danny...that's just an invitation to start doing a complete convex edge from spine to edge. I think eventually it becomes a matter of when you are polishing your blade you are also sharpening it.

If I have it right, you make a small sanding block, cover it in firm foam and go from there. Start with something like 400 grit (200 if you're in a hurry) and make the blade look the same all over, then go to 800 and do the same, then to 1200-1500 and do it again. You should have a nice satin finish and a decent edge at that point.

Guys, does that sound about right?
 
Danny?

:)

:rolleyes:

Then, top pitting hon hit.


Work on your sibilants this week, and be prepared for a quiz next week. And wipe off that knife!



(My Pen knife got its pitting scrubbed by strange man using the dust of Afganistan on the pits caused by monsoon rains in Nepal. Doesn't affect it at all.)
 
that was a linguistics joke.
very funny, kismyatt.

really though, near the cho there is some pitting that 400 grit paper would get rid of. i like the mirror finish it has, can a man get a mirror finish retsored by hand or with a dremel tool ?
 
Danny?

I wouldn't use an electric tool. It's far too easy to create more damage. The progression of grit grades of wet/dry work will address the problem, and give you some mild satisfaction of sharing with the kami.

I've only gone up to 600 grit, but others have done incredible work with the higher grit paper, creating or restoring beautiful finishes.

Have fun.:)
 
Yes Danny...it's just a matter of taking it up through finer grits until it's the way you want it. From my metalworking background, I know it's a matter of not going to the next grit until the surface is uniform.

I have the advantage of a buffer that I've been using for years and I was able to return a vinegar etch (wanted to see where my hamon was) finish to mirror in about 15 minutes. I used Tripoli, then white, then (believe it or not) Meguire's black scratch remover. My buffer runs off a reducer at 1550 rpm and it took little effort to get the mirror back. I spent most of the time on the Tripoli...maybe 8-10 minutes, then maybe 3-5 with the white, then not more than a minute or two with the Meguire's. Finished it off with Caranuba on a clean buff.

Now if I could just get that perfect convex edge...
 
thank you, that is closer to the help i needed.
i will give it a shot, but i might have to send it to one of you guys for some doctoring..

If you want it sharp on a buffer you need to use a hard felt wheel. They're a little spendy, but work like a charm.:D The soft buffing wheels seem to overlap onto the edge and prevent getting that "Full Body Shiver Sharp" edge.:(
 
Got to learn to put the full convex on properly first. I'm thinking about picking up an affordable belt sander this weekend. I watched Dan (on video) and it looked like too much fun not to do! *Then* I'll pick up the hard felt wheel!

I think that once I figure it all out, I can sharpen all the Khuks in the neighborhood and recoup my investment (well, maybe if I get more of the neighbors infected with HIKV).

:D
 
I haven't been able to reproduce the mirror finish using 1000 or 1500 grit. Perhaps I'm not patient enough. 600 to 1000 grit seems to leave a very nice, repeatable, user friendly finish, but not like a mirror.

I always thought a compound or buffing wheel should be used to accomplish that.

Rust should naturally be held in check by proper maintenance, but a little pitting is certainly not going to affect the knife's performance. If you use it well and often you can pretty much kiss the mirror finish goodbye, but over time it'll take on a different kind of "shine".

Sarge,
The "strange" man who used spit, a rag, and Afghani dust to polish the Pen Knife Kis was talking about. One of the very first batch that Bura made, and that while he was afflicted with a dangerous and debilitating bloodclot, that there knife is well travelled and well seasoned. It would hurt my heart to hear of the pitting ever being polished from it's good blade. That's not pitting friends, it's character.
