remove a chip from a convex gring

[Mad_Maxx]

I got a Blackjack Grunt a couple of days ago, nice beast for 21€
today I found a piece of wood laying around the house and wanted to try to "chop" a bit. ( it was ajous wood I think, that's what it's called here in Italy)
after a few chopping motions i saw a chip\nick near the tip, never sharpened a convex as this one is my first, I followed the info on the BRKT collectors site, I used a mousepad and some 1200 sand paper.
Afew touches on a COARSE stone and the sand paper restored it a bit but, there's still a visible nick I can feel with my finger, still slices paper nicely.
it's no longer a razor that shaves my arm hair but it cuts nicely,had to resharpen a good part of the blade so it lost razor sharpness but for the first time it's ok.

How do I remove the nick completely? just rougher sandpaper? will it remain?
is that normal for a convex? it was wood not steel I was chopping and I did it lightly, I'm sure I did not hit anything else than the wood block!
i'll add a picture tomorrow, it's night here

thanks in advance
Maxx

If it's a user I wouldnt't worry about a couple of nicks in the edge. You´ll sharpen them out along the way, but probably collect other nicks, chips or dents..

If you want the factory edge back, you´ll have to regrind the entire blade, and that´s not realistic..

i think you may have hit a pebble or something in the wood, that can happen sometimes.

i would suggest starting at about 400 grit and going up through the grits, hitting 600, 800, 1000, and 1200 optimally, but you can really skip a couple of grits if you have to.

don't do too high of an angle, lay the whole knife on the paper and just slightly raise the back. you might try the sharpie trick to see if you are hitting the edge. color the sidesof the knife near the edge with a sharpie and take a single pass on the paper. this will tell you where you are sharpening. sharpen until the nick is gone at 400, then polish with the other papers.

Don't worry too much about small nicks like that on a user knife. You will get plenty of them over time if you really use it and if you sharpen out every little one you'll end up grinding away half the knife before you know it.
