Scratches by the batches!

Today I got a kitchen knife from Wingnut. We discussed on the phone that it was okay to showcase his knife and the repairs.

The first step I want to do is get the scratches out. BTW, that black applicator is not a piece of the black obsidian brick! It's foam padding, the gentlest object with teeth I have, I do not wish to create more damage.

I have seven or eight polishes and emulsions here from Ken Schwartz. I'll keep putzing until I find the magic bullet. I want Wingnut to know the damage has been ameliorated as soon as possible to put his mind at rest.

Once that's done, the only other defect I see now is a slight issue with the right side of the tip. That's just a five minute job.

Did you all ever find the culprit?

Or am I thinking about another post...

No, this is one of those knives.

The good news is that within ten minutes I 'dulled' the scratches by at least 50 percent. Can I get them all out? Right now, I think it's just a case of elbow grease.

I believe I found out what’s making those marks but want to run it by Tourist first.

In talking to Wingnut, I believe these marks may be from the side edges of his stones or fixtures. These are called "compression marks," and that alone explains why I cannot catch my fingernails on the marks.

Here's an analogy. Imagine if you had a slight 'ding' on your car's fender. If you simply rubbed the mark with polishing compound, you'd wear off the paint, but the ding would still be there.

The fix would be to remove the fender and gently tap the ding back into place from the back side. Obviously, that cannot be done with a blade blank.

I've rubbed the knife pretty hard and dulled a few spots, but mostly it just made the blade blank shinier while the marks were still visible. I used to polish motorcycle parts with a motorized buffing wheel before we sent the parts out for chrome. That's the machine I need. I don't think a human hand can get them all out.

But it's a good knife, with one minor flaw on the tip. I'll see if Wingnut just wants the edge polished. Heck, he might have a buffing wheel.

A Dremel would be the perfect tool for that job.

Probably, but I don't own one.

Wingnut sent me one knife to experiment upon. He might have some of these things.

Update: I have asked Wingnut what kind of polishing equipment he has. As you know, Chuck suggested the mechanized kind, which I do not own.

Here's my concern, I've got some of the scratches out, but I think the rest need a deeper, harder method to remove. I told him I would happily sharpen/polish the knife, but I do not know if that would make buffing it harder when he gets it back.

There's one spot on the edge that's a little deeper than the rest of the bevel. Using east-to-west strokes that comes out easily. The tip needs about five to ten minutes work.

He and I will work this out, the job at my end is just an hour or two.

When I moved to Tampa I had to drastically downsize and yard sales got rid of most of my tools so no I don’t have any polishing equipment. We have found the culprit of the marks to be a new sharpening stone I had to buy so I’m not going to use it again. I’m greatly appreciative of The Tourist for all the time and effort he has put into this project, he is an expert and Is more than willing to help others.
Age has given me absolutely no patience so I’m going to farm out the future sharpening of my knives to a professional, any takers, hint hint.

...I'll get on the one you sent me right away...

It's already inked and the stones will be soaking soon.
