I thought it might be time for this again since Ron has become a potential victim of HIKV and also now that Bob has decided which khukuri he is gonna get 1st.
And for any lurkers that may be new and haven't seen it before.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

There is very good information in Howard's Khukuri FAQ's and the links there to get a khukuri or any knife as sharp as it could possibley be and to maintain the edge bevels that came on the knife. However this question keeps getting asked again and again so I will try to make it simpler for the sharpening impaired.

It doesn't take much in obtaining the tools I use in sharpening all of my knives.
These items are what I use in varying stages and depending upon the condition of the edge that's needing sharpened. And I can cheat by using my Grizzly belt sander, but that is seldom needed after a good edge is established unless you badly impact it on a hard surface. And even then the tools described below will do the job needing done.

You already have a steel in the form of the chakma or the hard back of a good knife. I am fortunate to have a solid piece of smooth round carbide that was used to make metal cutting tools from and mounted it in a brass handle. A good smooth steel is optional since you can _make do_ with the items above.

Get yourself two or three _good files_like the Nicholson Black Diamond brand in lengths of 6"-8" and 10 inches.
If you only get two then get the 6" and 8" as they are the handiest to use. Get yourself a good _file card_ to maintain your files properly.
The best ones have a brush on the opposite side of the wire cleaner which looks something like a wool or other textile carder.
A file with a piece of metal embedded in it will cause gougeing and eventually ruin your file by picking up even more pieces of metal.
Take care of your files as you would any other fine cutting instument by keeping them free of rust and insure that their cutting edges are protected when put up.
A _good file_ is invaluable in maintaining the softer areas of a khukuri's edge.

I like the DMT duofold diamond hones as recommended by Cliff Stamp. They come in several combinations, but one only needs two, the Black and Blue and the Red and Green. The Black is the coarsest and the Green the finest.
Now for the strops.....
You can get some nice leather and make these yourself or you can buy them from sources on the www.
I have found for khukuris that the best size is about 1" to 1/18" wide as this will let the strop get into the recurves nicely.
I like mine glued onto a piece of wood as I think it makes them easier to use.

Now to the sharpening technique.....
First work out all the dings and impacted areas you can by using the steel or other hard surface like the chakma or the hard back edge on a knife.
You will be surprised at what a good steeling will do to bring back an impacted edge.
I brought back the edge on the HI AK Bowie after cutting a soft 3/8" carriage bolt in two with a vise to scary sharp with no other work needed.

If you still have areas that you couldn't steel out then take your file to the edge trying to maintain the original convex edge. Anyone can do this with a bit of practice.
Use the file the same way you do a hone and produce a burr on one side and then the other to insure that you indeed have a true edge to work with while removeing all the dings.
You may not get all of them out in the "sweet spot" with the file so that will be accomplished with the hones.
The final burr is to be honed off.
With the khukuri restored to its original shape and edge and with all the dings and other mishaps worked out you are now ready to proceed with the hones.
Depending upon the edge you have managed to produce with the file will determine the correct hone to use.

The Black DMT hone is _very_ aggresive and a light touch is all that's needed to reform and produce an edge that's ready to be properly sharpened with the finer hones.
The same technique that's recommended in all the FAQ's is used to produce a finer and finer burr from one side to the other.
I find the Green hone to not be needed for most work on a khukuri, however I do use it to produce very fine edges on thinner blades.
After you have proceeded this far and have established a proper sharp edge you are now ready to strop off any remaining wire edge. I have for a long time now used two strops, one charged with Tripoli and the other charged with Jewelers Rouge.
These are adequate and will produce a very sharp edge, however I have discovered like many others before me that a Green Chrome strop will produce the finest edge that I am able to make on any knife.
Starting with the Tripoli strop drag your khukuri with the edge trailing, so as to not cut the strop, back and forth several times until you strop off the wire edge.
This is done with the khukuri held low as Cliff states in Howard's Khukuri FAQ's.

When you have removed the wire edge proceed with the Jewelers Rouge further polishing the edge of the khukuri.
When you are satisfied with that polish proceed to the last and final strop charged with the Green Chrome and put the most incredble edge you have ever made on you favorite khukuri or other knife.

Cliff has stated the proper ways of maintaining the convex edge or putting a flat beveled edge on you knives in the khukuri FAQ's so I haven't and won't get into that.

With practice anyone can maintain a proper convex edge with the tools described here. And with even more practice you can maintain a flat beveled secondary edge on any knife.

In Ed Fowler's book he has a picture of a smooth Wyoming river rock that he picked up to sharpen one of his knive's on in the field and that shows that nothing spectacular is needed to maintain the edge on any knife.
Ed likes the convex or "Moran" edge as do I.
All of my using knive's have been converted to this style edge as I personally feel it is the best edge that can be put on any knife and it will serve you well for a longer period of time than any other method.

If you are unsure of yourself and your abilities the trick is to practice, practice, practice!!!! Get yourself some cheap knives at a flea market or other source and use them to practice on before moving on to more expensive blades.

You will get better and better as time progresses and if I can learn to do it by hand anyone can.

YVSA, thanks for the post, this will help alot. I too have a couple of carbide rounds from when I was in tool & cutter grinding but they have been ground into scribes...hmmm now that I am retired I don't need a scribe anymore anyway

I also found a couple of rounds of T-15 tool steel, how will these work as a burnisher on the Khukuris steel.
Ya know I think the HIKV can be transmitted through the compter

Thanks for the info.
There are plenty of forums out there who would have forgotten about me by now.

Ron the T-15 should be excellent for smooth steels for any kind of knife blade.
When I was forced to retire in '95 it was one of the best tool steels out there IMO. We used it almost exclusively in our auto screw machine dept.
IIRC the T-15 is around 65 Rc but the memory is also not as good as it once was either.
smile.gif

The last year I worked it was in the tool crib as a tool & cutter grinder and I also had the responsibility of ordering much of the tooling.
All the lead men and shop guys liked me because I didn't stint on the tooling. I was the 1st one to get Gurhing Drills in the shop in a steady supply.

And Bob no one here hardly forgets
anyone who asks which khukuri to buy 1st. We know the signs of Pre-HIKV.

One question, what's the V in HIKV.
I assume it's Himalayan Imports Khukuri something.

YVSA, you and I have the same mentality when it comes to tooling. I was a nuclear machinist (ie monel, K-monel, 300 & 400 series cres, inconel, etc.) so I know the importance of THE BEST TOOLING. All my drills are cobalt or Ti coated hss. Any man who works in the tool room and orders "the best" has my thanks!!!

Thank you Ron.

The guy that supposedly "worked" in the tool crib before me got a bonus if he didn't spend over a certain amount and accordingly there were a lot of Silver & Demming(sp) drills in the machines.
Needless to say I never got a bonus but the guys had what they needed to work with.
smile.gif


We worked with some of those materials occassionally, but not too often, but another shop where I was the leadman over the asm's we made a lot of valve parts for the oil patch and used a lot of monels and such.
The only time I worked on any nuclear stuff was in yet another shop that found out I knew how to run the little Swiss auto's and they bought a brand new Tornos for a job they got from Kerr-Mcgee, Interesting work.

The reason I liked the asm's was I had a lot of goof off time that I could play with my knives and such.
It was nice having access to some nice machine tools to play with them on.
smile.gif

And I learned a lot about sharpening that has served me well with my hobby.
The khukuris can be a little tricky though since the blade isn't fully hardened its entire length.

Yvsa, I suppose this discussion is "off subject" but the last place I worked as a machinist was at a Boeing sheltered shop. They bought me a brand new Hardinge 4 axis CNC milling center and told me to learn how to program and run it....I did!
21 horsepower, 8000rpm, and 4" diameter cutters....man that machine could move some metal.

I am wondering how do the Kamis zone treat the Khukuris and how do they know what the Rockwell test is? In some of the pics I don't see any Rockwell testers. Are the khukuris oil tempered, water tempered...or? Do you think that Uncle Bill can get me a khukuri that has a fully hardened edge but softer spine?

If you would rather answere me via email about the off subject material, that will be fine with me.

Regards;

Sweet machine Ron!!!

Uncle Bill can best answer your question about a fully hardened edge, but you might want to really think about that 1st.
I was thinkng that a fully hardened edge would be better too until I was here for a while and learned just what a khukuri is designed for.
smile.gif


And if you haven't checked out the H.I. Website you are Really Missing something!!!!
Check on any of Uncle Bill's or Rusty's post and you will find a link.
smile.gif

It will answer a lot of your questions.

Ron, somewhere I think I have pix of a blade being water quenched which is standard. They judge the edge hardness with a file as I do here. They are shooting for 57 or 58 to 60 Rc and generally get it but they have never heard of Rc.

I tried to introduce transmission oil as a hardening medium but they wouldn't stand for it.

Uncle Bill and Yvsa;
Thats what I am here for to learn more about my new virus and how to deal with it.

Thanks loads for your return comments, I visit here several times a day just looking forward to more information.

Yvsa, I visit the HI web page many times a day but I have to wipe off my keyboard too much now...slobber, slobber, drule!!!

Yvsa;
When using a steel on the khukuri blade, do you "push" it from the spine to the edge as if you were stropping by hand or do you hold the steel and draw the edge along the burnisher as if you were using a butchers steel? Or do you use it more like a file and just work on the dings until they are flat again(concave)?
Hope I am not bugging you with all these questions. I read the threads about sharpening but still have yet to get a picture of it in my head.

No problem Ron.

If there are heavy dings I use the chakma to push them back into shape and as Bro says, "It takes a lot of pressure."
You will be surprised at how much material you can move around with one of those little tools! Takes a little patience sometimes though.

And I use different ways for whatever seems right at the time and condition.
If it's just to align the edge I push in longer sweeps away from and along the edge with a light touch.
To put it in another light think of tapping an 8/32 lefthand thread on a 1 3/4" dia capacity Wickman bar machine. Great big machine and a very light touch.

And they said it couldn't be done.

Yvsa, I finally got this information incorporated into the sharpening section of the FAQ.

Ron, Good to see you here. Lou said he was going over to visit you. Did he make it? Perhaps together we can convert his heathen soul to the way of the khukuri.
 
Howard;
Yes Lou made it over here along with one of the other hoodlums...."woodyworker.." or something like that (Brent Van Zanen). In fact I did a trade with Brent for my village khukuri (18" suripati style)and thats what started this khuk-fire inder my butt. I think Lou will be a hard sell into kukdoom.
Hey, I am finding WA helpers all over the place now....so why not HELP ME WITH THIS HIKV....its gonna get costly.
