Sharpening question

[sfs08]

So I just got a delica4, in vg-10 steel, and needless to say, I am quite the beginner with sharpening!

Let me begin by saying that all I have is a lansky system, and I can't afford a sharpmaker so please don't recommend that.

I have a coarse stone, a medium ston, and a fine stone.

I've been able to put hair-popping edges on my sak's, as well as my 110.

When I tried to sharpen it, I just dulled, literally dulled the delica 4!

I worked both sides with a coarse stone til I got a burr, then worked it with the fine stone until the burr was removed, which I always did with the other knives.

ANd it got dulled!!

All I can do is buy diamond stones, so with that in mind please try to help me!

Thanks!


And I sharpened it with the 20* slots, as I cannot use the 17*.

This should really go in the Toolshed.

I'm thinking when you removed the burr, it took more metal with it than just the burr. It took a bit behind the burr, resulting in a dull knife.

There are better explanations in the Toolshed area.

I've dealt with the phenomena with stainless alloys, as some are "stringy."

How sharp was the blade off of the coarse stone? Could it slice newsprint? How exactly did you remove the burr with the fine stone?

ANd it got dulled!!

What exactly does this mean, how specifically are you determing the sharpness?

All I can do is buy diamond stones ...

You don't need to buy anything.

More than likely there is a tiny tiny burr there that you are not seeing without some kind of magnification. Harder stainlesses like ATS 34 or S30V will do that, and if you can't see it or develop a "feel" for it, you'll think they're duller, but it's really just a micro burr rolled over. Get a magnifying glass and look very closely at the edge, preferably outside in the sun where you can see without shadowing the edge. D2 is bad about a tiny burr also, I just strop it off on an old belt and then hit the edge a few more times gently with the fine stone (I've got a Lansky system also) and ultra fine, and usually always end up with a blade that will shave hair, bite your thumb, ping string in two with little effort, and shave paper into little bitty confetti curls.
