Lansky isn't foolproof...I am that fool.

Knife in question is a SOG Twitch II. I don't know much about it other than it was given to me at Christmas.

It shares pocket time with an old Elishewitz Benchmade I picked up years ago. I switch out both as my EDC.

Last night I decided I was going to touch up the SOG a bit as it has become a bit dull.

I chose a 20 degree bevel as this isn't a hard-use knife and tends to pull duty cutting boxes, opening letters, etc.

I followed directions, pushing each stone towards the edge at a slight angle, lifting up and starting again.

I wasn't sure how many passes I should make before flipping the blade, so I waited until I could see a "fresh" edge and then flipped it over. I repeated this with the coarse, medium, and fine stones.

Now, I could feed a baby green bean sauce rom the tip of my knife without fear of cutting him. Might make a dandy signaling mirror too.

What have I done wrong here?

I've read the tacked thread up top, but it offers absolutely no help in the sharpening department.

Am I asking too much out of the SOG? I touched up my Benchmade and it took the edge fine (although I believe I used a 25 or 30 degree angle on it), but is has been years since I've done that.

Any and all help is very appreciated.

don't move on to the other hones stick with the coarse until you have ground all the way to the edge. Easiest way to know if you grind off enough steel is to look for a burr on the other side than what you are grinding on. I suggest doing about 50 strokes on one side then switch to the other side repete this until you have a burr along the length of the edge. Then you move to the next stone.

alright then.

Maybe I didn't make enough passes. I think the orignal bevel was at 30degrees...If I'm going to reprofile the edge (which is what 'm doing) I've got some work ahead of me.

Thanks for the advice.

I would suggest using a Sharpie black marker and blacken the edge and use the coarse hone till all the black is gone. Blacken the edge again and use the next hone. Follow this till you have the blade sharpened and then lightly strop. This will let you know each hone has removed the proper amount of material and you are ready to move to the next finer hone...

Thanks this will help when I get home.

Well, it was as I figured.

Afraid to take too much off, my first attempt just didn't work.

Last night, I sat down and sharpened with a purpose and my results were much much better.

Thanks for all the help.

Sounds like you got it figured out. I was going to add that my Twitch II matched up perfectly with my Lansky's 20*. And the SOG steel takes a fabulous edge from it. Make sure you either use the same "rod" with all the stones, or make sure all the rod/stone pairs look the same when laid flat on a table. Wasted a lot of time figuring that one out.

With the lansky I would use a back and forth saw motion, till I got a burr IMHO that's what its for, the ability to just grind without screwing up the bevel. I then prettied it up after with the strop. But, I prefer freehand and sandpaper now, after I learned how to keep angles.

Good point on the rod angles.

I noticed that the Lansky attachment method leaves a lot of room for inconsistencies.

the knife is pretty sharp now, just took some time.

I'd like to get a strop, but I still need a bit of practice prior to tackling some of my more expensive knives.
