Hell Razor....Edgeart. (Pics)

You guys motivated me...

I went back down to 1500 grit and worked out a few flaws that you needed a 4x magnifying glass to see. Then worked back up through 3000 GRIT!.

Did you know that Busse coating will take a POLISH? The edge polish now extends back a good bit unto the coating. It looks wild but I could not get it to show with my Camera a lighting.

I have a fresh piece of leather and some super fine diamond dust. I looked for a long time for diamond powder this fine and I have been saving it for the right project. I will try to get a picture that shows the blade polish extending into the coating...

I would love to get this highly refined edge to Vassili For a thread test.

Wow . . . that is an impressive looking edge! But is it more likely to break under hard use now?

Well that is open to debate. Unless you define hard use any knife can be broken. This edge will certianly hold up to any task a knife should be used for and then quite a bit past that.

The Hell razor is a fighter made from INFI. It also is very useful for general knife tasks. For instance today mine thin sliced a tomato for a BLT sandwhich far better than the stock edge did. It was a very tough tomato but the Hell Razor came through just fine. :D

I have found counter intuitively that in general finer edges last longer in use.
Less force needed, less total slices or cutting strokes and after my edge degrades a great deal it will still be sharper than most out of the box edges.

Here is a return question for you.... Put on a thick leather jacket. Then on a table I will place a stock edged HR and my reworked HR. Gaze closely at each blade. Tell me which knife if given a choice you would rather have slashed across your leather armored chest? Just one hard fast slash.

On the other hand I profile the edges of big choppers somewhat differently.
 
Added a sort of artsy looking picture to the first post.

I like macros of blade edge close ups... yeah I am weird that way.

No bid deal. Just got laser eye surgery the other day and I am just waiting for it to heal up before I start grinding again.

if they haven't mentioned it, be prepared for blurry/changing vision for about a month (getting less and less over a 6 month period), and dry eyes. lots of dry eyes.

The place I went to (san jose laser eye center) did a great job on the procedure, but gave almost no information about what the actual experience was going to be like. they basically were a revolving door lasik facility.

you'll more then likely find that when your eyes get dry, they will star blur bright lights into random directions. mine tended to blur it downward and to the left. about 3 weeks after the surgery, when I went back for a check up there was a point at which I thought I was going to crash my car because every singly light that was reflected on the rain drops on my windsheild was blured across the entire top to bottom line of sight. I could see just fine, it's just that light was heavily distorted.

It's been over a year now, and I don't really have any vision problems, all of the light distortion having gone away, unless my eyes are really dry.

but I still wake up with super dry eyes every morning. buy lots of preservative free eyedrops.

my original perscriptiong was (Left) -5.00sp -1.00cv, (right) -6.00sp -1.00cv, and I'm now at 0.00 across the board, 20/20 with dry eyes and 10/20 with well moistened eyes. so it was definitely worth it, even with the scares and constant dry eyes.

By "hard use" I meant: could you chop down a sapling without rolling the edge? Please DON'T risk ruining that beautiful edge to test this, though!
 
Looks great. Now you have to abuse it so you have an excuse to strip it and polish it up. And then post more pics of that. Man I should have stocked up on scrap diamond grit from my old job. We had a lot of the stuff that would have been perfect once it got contaminated etc. All sized of grit up to stuff finer than baby powder. That would have been so usefull (of course I did not think of it for the 5 years I worked there).

no reason to put a fancy edge on a hard use knife if your not going to use it hard :D

Well, it seems like it might alter the functionality of the blade. Reminds me of an old movie I saw years ago. These two swordsmen from different cultures both think that they have the finest blades and decide to hold a public demonstration. The westerner takes his massive 2-handed broadsword and uses it to cleave a pair of shields in half. Then the Easterner draws his thin scimitar and tosses a silk handkerchief in the air, letting it fall across the edge which slices it neatly in twain.

What I'm thinking is that a thick heavy duty Busse is like the broadsword, but the already thin Hell Razor with this modified edge might be more like the scimitar -- great for slicing through heavy materials and such, but might fail if subjected to the stress that a camp knife might be subjected to.

That being said, I think that the edge on that Hell Razor is really cool, and I'm assuming that the INFI would make the razor thin edge more durable than a similar edge on a knife of inferior steel.

OK so I need to test this edge on some branches and maybe chop a 2x4 in half... I will let you know if there is any edge damage but I REALLY doubt it.
plenty of meat left.
 
the big question is "HOW LONG DID IT TAKE???"

and I have an issue with cutting stuff with such sharp edges because they roll too easily, but I've never had an edge like that outta infi.

I'd like to see the results of your testing

Well it used to take me hours and hours to do edges like this. I can spend a entire day doing one FFBM for instance. But this knife took about a hour and a half starting with a 120 grit Dia-sharp stone from DMT. That THING eats metal. Then i just run it through 5 grits of diamond stone holding the angle and just long enough to remove the scratch pattern from the previous grit. Then I drop back down to 600 grit wet dry, then 1500, 2000 ect. Spend about 5 mins on each grit.

Its shaping the blade with the course stone that takes the most time and work.
 
[this post has been edited because what I posted was silly]

unless the edge has been made super thin, any damage incurred from general wood working should be reallignable, dents,rolls, and mashes being less then 1mm deep. if you've made it straight razor thin, then yes, it will probably get horribly messed up during hard use :D

I don't think cutting down saplings would be considered hard use. Green saplings are quite easy to cut down. Dried 2X4 would be harder and dried knots would be considered pretty tough on thinner edges.

LVC,

Yeah I know what you mean about the dry eyes and starbursts. My starbursts have been reduced significantly in the last few days so that is a good sign. My vision is probably a little better than 20/30 right now. Hopefully it will settle down to 20/20 :D
 
That edge looks great... just a question: how many times did it bite you in revenge for so much sanding? :D
Great job,
Mikel

EDIT: Just noticed someone else asked about how long did it take you...
