hey guys, this is my first knife. Made out f O1 all handmade with micarta scales.

Sharpened it up today and from the moddle to the tip it looks gorgeous. Smooth, no scratches on the edge. Razor sharp. However, my issue is with the section of blade in this area. From what i can tell my inexperience coupled with a tiny 1x30 belt sander caused me to mess this part up. This section of the blade is may 5 thous more narrow than the rest.

My question is how to mitigate this without having to regrind the entire hardened bevel. Can i just work it out on a coarse stone?

The knife turned out wonderful! I can see many errors, amd how i caused them and how to fix them. I just need help on this part.

I have like 25 hours in on this and i dont want to throw it away.

Thanks!

Junior

jlopela,

you can work it out on a coarse stone. Be careful and precise with the angle. Then move to a fine stone. You can even finish it up on sandpaper mounted to a flat surface in the higher grits beyond what a fine stone might give you. The knife looks good. It's definitely worth the time you take to fix it.
 
Thanks i4Marc! I was hoping that was the case. I worked it for a long time on the coarse stone, just decided to stop until I consulted more experienced people :)
 
Well, experience is relative. I've been doing this for a couple of years but I have a pretty good grasp of the basics. Hopefully more experienced people will chime in. I realize that working with a 1X30 is probably a case where jigs are beneficial. However, I say the following to the new guys whenever the topic comes up about using jigs. I think you have found out first hand about the shortcomings of using jigs. I recommend to learn how to grind freehand before starting to use jigs. It takes a while to get up to speed and comfortable grinding freehand. But once you learn the mechanics and the "feel" of it you will likely never have your same problem again. You will be confident putting the blade back on the belt and you will know what you need to do to fix most problems that arise. It's like learning to swim. Sure you can just get a row boat if you don't know how to swim. That will get you across the lake. But what happens if you fall out of the boat? Take the time to learn how to swim. You will never fear falling in the water again.
 
Yeah, definitely thanks for the help! I made a jig and was going to use it, but the tool rest was just horrible on the 1x30 and the jig wouldn't slide accross it. I would have had to make a whole new tool rest, so I just freehanded it.

I went back to the 1x30 today and re-did the whole edge, then realized i think that most of my issue was i didn't have the edge thin enough right next to the plunge line (i think that's called the ricasso? not sure) so it was causing the 1.5" wide sharpening stone to not make contact with the entire cutting edge.

I took a very fine file and gently knocked off a little bit of the edge by the plunge line and i was able to get the entire length of the edge sharp enough to save with.

Thanks so much for the help for confirming what I was thinking, that i just needed to work it longer.

Take it easy!
