Modifying an HI knife edge to meet my expectations...

I had shared this on another khukuri forum, but felt it was just as appropriate here......

Since I buy these khukuris for collecting only, I do not like to alter them in any way. Even though it’s rare for me to do so, there are times I’ve made an exception to this rule.

The Himalayan Imports factory edge on my WW2 model, and it's sharpened accessory blade, was something that bugged me too much to leave it as it was. The original HI edge on this knife looked as if it had been done after the blade had been highly polished. This left the edge pretty sharp, but it did not look as nice as on the other brand khukuri specimens that I own. The others seem to have all the sharpening done before the final polish is performed on them, leaving a nice smooth and sharp edge.

I put some good thought behind any possible modification before I decided to approach this task. Once my game plan was calculated, I went to work on it.

I masked off the entire blade and handle, except for leaving about 1/8" of the entire edge exposed. I then went to work on the edge using a very fine grit emery cloth (grade was not marked, but I would guess it to have been in the 700 to 900 grit range). I used this emery cloth supported by a cushioned home made sanding block. I then went with some soft cloth that I rubbed briskly against a finer grit polishing compound, and used it on the area that I had just used the emery cloth on (using the same home made cushioned sanding block as it's support). I then did the same thing again, but with an even finer grit polishing compound. Then I removed the tape and paper wrapping I had on the knife, and went over the entire blade area with some Flitz polish. This was done on both the main blade and it’s sharpened accessory blade.

Here is the “before” edge on the main blade (the original HI factory edge):

Here is the “after” look of the same edge after I performed the work on it:

I kept it sharp, but not overly so (just right, IMO).

And now, when I wipe these blade edges down with a silicon cloth, it feels like I'm wiping down smooth glass,............ not like before, which felt more like I was wiping down the edge of a fine toothed hacksaw blade!

I’m definitely happy with my results! :)
 
Great job! Which direction were you rubbing the abrasives? I would think if you were rubbing along the length of the blade there would be a tendency for the blade to bite into the sanding block.
 
I have never seen an edge like the one before you fixed it. It looks like someone took a file to it.
Hi edges are generally so hard (except near the cho area) that you can't cut them with a file.
 
olpappy,

Thanks! :)

I went with gentle strokes from spine to edge direction (not blade length/bolster to point direction).

I only own the one HI WW2, Arty, so I don't have other HI's to compare it to.
I do have other khukuris from another manufacturer, and they all came with the type of edge that I "now" have on my HI WW2 after doing the work on it.

The knife was purchased here on this forum from Yangdu via a DOTD ($100).
It was not listed as a blem or anything like that, and I believe HI sells this same model for $125 off of their website, so I believe it was just a standard DOTD knife.

Maybe the high polishing process caused a bit more dullness then they had hoped for on this knife, requiring them to have to give it another touch up sharpening after it was polished,............... but that's only speculation on my part, since I really don't know for sure why. What is sure, is that it definitely received a sharpening at the HI level after the final polish was performed on it. Whether it was done in Nepal or in Nevada, I don't know, but it was surely done.

This knife did also come with a dual kami marking.
Though it's a Bura made and initialed khukuri, it came with Bura's crescent moon and Sher's rising sun engraved over one another.
 
I've gotten plenty of HI Knifes with the first edge, so I don't think it is unusual.

Thanks for sharing that with us :)

I was starting to worry that maybe it's just me that gets all the one of a kinds in every respect when I order things (like the kami marking fluke) ;)
 
:thumbup: I've never had a grainy edge like that but I've had my share of uneven or too steep edges. I always sharpen the edges till they suit my style
