I have made my first attempt at putting a new convex edge on my High Street.

I used the mouse pad and sandpaper method. I was able to get it sharp, but not scary sharp. As the pics show, I also put some ugly marks in my nice satin finish.

Anyone have any sharpening pointers for me, before I do further damage to this beautiful knife?
 
On the sandpaper/mouse pad technique, make sure you are using a light touch. You want to work up a nice wire edge before moving on.

What grit are you using?

Make sure you get the wire edge before moving on in grits. I have gone from 160 grit straight to a strop once I got a wire edge, hair popping sharp.

I usually go up to 600 grit before stropping.

Also make sure you use a really light touch on the strop.

What kind of stropping compound are you using?


That is a way better strop than I use, and I imagine you are using a much better compound.

I used grits from 120 to 2000. The compound on that strop is the chromium oxide from Hand American.
 
Nice first. Next time give blue painters tape a try to avoid any ugly scratches. Cover the body of the blade, leaving the edge bare with a little extra room or you'll be sanding tape. -----gl
 
Great job you did there. Can you please give some details on the materials that you have used? Which brand of sandpaper? Which grit? Did you use a leather belt at the very end? I am very interested in putting a convex edge on my Sus Scrofa. Thanks

I used 3m wet-dry sandpaper in 120-400-800-1000-1500-2000 grits on a mousepad. I used the strop in the photo for the final polish.

Heyday, Where did you get your Paddle stropper? did you make it?

Yes, I did make the strop.
 
I have done a few folders this way. My sebenzas especially. I find it is very very easy to do. I practiced on a friends folder first but even that turned out well.

Not sure what pointers to give but what Rolf said makes sense. Stay with the original grind. It will be easy to feel the right angle if you do. Once you get the feel of it I found it can be done very quickly and easily.

I got an edge on my regular sebenza that could sit next to an edgpro edge and look about the same excpt convex.

It really is not rocket science and I say that in a nice way because when I came on these boards and all the nice folks started helping me learn to sharpen I initially thought there was some serious technical wonders!

Now I know it is so easy that even I can do it. raise burr/remove burr/done :)

it looks good from what I can see on my blackberry :)

And btw, I am with Rolf again, I care about how my edges look user or not. If I wanted crap edges I would stick my knife in one of those electrical sharpeners and shake it around!

Scratched blades cut just as well ;)
 
I'm going to go with if you can't control your sharpening enough to come up with a decent looking edge then you can't get it as sharp as a more consistent sharpener.

Blinky smiley :)
 
My bevels look horrible because I don't care about looks, but my microbevels are very clean and precise, and sharp enough to whittle free standing hairs multiple times in the same section and push cut circles through receipt paper. Scratches on the blade profile don't affect the edge, which is the only part that really matters :)

Behind the edge, getting it thin is what makes it cut well. Not making it pretty.
 
I guess everyone has their own ways. Sloppy is not mine if I can help it. :)

I wasn't talking about scratches on the sides of the blade. That would be silly.

All I am saying is the more precise the better. Why be sloppy part of the time if you can help it.

When I convex I am not really putting multiple edges on the knife. Just one. Or so I think.
