Ray is this blade coated or plain? You could take it to a buffer and use various compounds to polish it out. A used 400 grit belt on a vertical belt sander is what I use for my final grind. Often times It does not need to be polished on a buffer depending on the belt. If you have a buffer or belt sander available I think you could get the finish you want.
One word of caution here--- Tape up your edge a little and make sure the buffer is taking the blade away from you when you polish. The last thing you want is a sharp knife hurling towards you when the buffing wheel grabs it and it will if your not careful. |

Thanks for the 8nfo Tacklenut. It's a plain blade. I have a grinding wheel, but no belt sander. The blade is A-2 tool steel, I was wondering if I could get a buffer wheel for the grinder and buy some polishing compound?

you can get buffing wheels at Harbor freight with polishing compound. Start with one wheel with aggressive compound and then go to different wheel with a finer grit. Polish the course in one direction and then the finer grit cross wise to that if you can and see what that does. A2 is good steel. I use it a lot.
Give us an update with your results. |

If the blade is as rough as you claim all you will get is polished scratches if you buff it. In order to get a good finish you will need to hand sand the blade with a wet/dry sand paper. I come off the grinder at 400 grit and start my hand sanding with 400 grit and work my way up in 200 grit increments. Once I've got to 2500 grit then the blade goes to the buffer. If this is going to be a working knife I'd hand sand it to 600 grit and call it good. It would never touch a buffer.

I don't need for it to be polish bright, I just want to get rid of the thick grind marks. What brand/type of sandpaper and lubricant do you recommend? |

I'll update you guys. I really dig the blade, overall (hell, it's sitting on my chest as I type this on my phone, in bed,lol). I just don't want to blur the sexy lines on it. |

I've taken up knife making after Ciraxis' thread so not terribly long. I'd use a sturdy sanding block, some 220 and 320 sandpaper with wd40. I currently have problems keeping the top of my grind line crisp during sanding. I'm ending up rolling over the top edge of the grind and making it less crisp. With the blade being heat treated that may be less of an issue for you. I haven't reached getting any blades heat treated. |

Although I'm a little nervous about losing the nice lines around the false edge and point so I might just start with 600. |

Amazon sells 5 sheets of 3M 400 grit for 8 bucks. The box stores will certainly ask for more than that. Depending upon how deep your grind marks are 5 sheets may not be enough. If you are planning on starting with 600g it will not be enough. Supergrit will sell you 10 sheets of 400g for $3.75 Supergrit |

The grind marks don't look too bad, they just feel horrible. I wish I could post pics and get y'alls opinion. I guess the Effingham blades were finished a little better, from pics and videos. ETA: oh, and I bookmarked the supergrit site, thanks!
