That's shiny! Mind do a knife for me, or ten?

Thanks jztml. I have been wanting to have a go at my Umnum for awhile now but was really afraid of messing it up. I thought what the hell. I practiced on my Cara Cara2. Here is a shot of how it turned out.

How long does it take you to do one knife? I find myself actually skipping steps in sharpening now, since while that level of sharpness is cool to look at, it's not that much better than a "sharp enough" knife in actual use, and cost a lot more time to get it.

That makes my Sebbie edge look like a POS.

Awesome mate.

It took about an hour and a half. The repofiling of the bevel took the longest. Followed by the polishing. All in all I went through seven different grits. I took my time this being an Umnumzaan in all. I really didn't want to mess it up.

Thanks Ben for the compliment.

Did you use some sort of jig, or was it freehand?

Jig to set the bevel with the coarse and fine stone. Then moved on to the extra fine and extra extra fine stones freehand and tried to match the bevel the best I could. I then polished with three different strops at lower and lower micron count. All done using DMT products.

It's very, very impressive Prime.

That looks sweet, Prime! That really is a work of art... and patience!

Thanks guys.

I just did my two Spyderco Manix's. And I have found that taking a picture of a mirror edge is just as had as getting one.

It's ok Ben just send me your Sebbie and I will sharpen it for you.

Benner · **Reply #42 on:** October 11, 2010, 12:15:50 AM

You know, I would if I didn't think customs would nab it.

In all serious I would be afraid of messing up someone else's knife. Especially a Sebenza that is beloved like yours. You should have seen me sharpening my Umnumzaan. Every stroke on the stone was like in slow motion. I so was afraid of making a mistake.

It's okay, put me as the return address and I'll even cover the return shipping.

You're all heart you.

jzmtl · **Reply #46 on:** October 11, 2010, 12:44:19 AM

What if it's sent back as a bag of parts?

Benner · **Reply #47 on:** October 11, 2010, 12:46:11 AM

It should be fine, but it's not a knife I'd even consider risking.

prime77 · **Reply #48 on:** October 23, 2010, 09:04:15 AM

For no other reason than to make Benner mad.

jzmtl · **Reply #49 on:** October 23, 2010, 09:40:37 AM

Nice, I just got a 1x30 sander, so hopefully I can duplicate that one day.

Benner · **Reply #50 on:** October 23, 2010, 09:47:11 PM

Dude!!

Fantastic work as always. I'm not at all jealous...

MultiMat · **Reply #51 on:** October 24, 2010, 05:31:26 AM

With my Sharpmaker & my leather strop I can get almost all my knives shaving sharp , it would be brilliant too be able too lop trees/hairs with my edges, hopefully one day.

I tend to struggle with smaller blades for some reason , my Gerber Curve & my SOG ToolClips small secondary blade are conspiring to drive me crazy, I just can not get them sharp

Prime the force is strong in you

I did this lastnight.

You have to keep those tips sharp.

What a coincidence; i also just finished sharpening a user Umnumzaan, for a fellow forumite on the Dutch knife forum.

prime77 · **Reply #55 on:** December 22, 2010, 06:04:12 AM

kwakster those are great shots. My camera is showing it's age and I have to put a magnifying glass in front of the lens to get close up shots. It looks like you went with a lower angle then me also. Mine is around 40 degree inclusive. What did you go with?

kwakster · **Reply #56 on:** December 22, 2010, 08:04:19 AM

The edge on this Umnum has been reprofiled to an even 34 degrees inclusive.
The convex factory edge changed angles over the length of the blade, when touching it up on a Sharpmaker only the straight part of the edge could be sharpened; the belly was way to obtuse so only the shoulders touched the sticks.
Of course reprofiling up to 30 degrees inclusive the Umnum would have been an even better cutter, but then the bevels would have become quite wide because of the thickness of the belly.
And because it's still a tactical knife a little stronger edge fits the bill well.

Did you use your paper wheels to sharpen her?

kwakster · **Reply #58 on:** December 22, 2010, 10:29:45 AM

No, all work was done on my first generation Wicked Edge sharpener.

What did you use to polish the edge? I didn't know the Wicked Edge went that high in grit to get the mirror edge.
