1. Haziness in the wood finish. It has 7 coats of tru oil. I did not like the glistening look of the Tru Oil, so I tried some hand-rubbing. I don't have a buffer.

I tried 0000 steel wool. I tried wet sanding with 1000 grit, 1500, then 2000. I tried car care pro ducts: rubbing compound, plastic cleaner, swirl remover and Protect All. I tried "shoe shine" rubbing technique with soft cotton rags.

2. Dark areas on the blade. This was left when I removed the masking tape. I guess it is adhesive residue. I tried rubbing with acetone. Maybe just more rubbing with acetone?

Any ideas would be appreciated.

What kind of metal is the blade?
 
It looks like the blade formed a patina where the tape was. Could be wrong though. I would think acetone would have taken it off if it was residue.
 
The dark stains are probably some patina,I never put tape directly on carbon steel blades,wrap a piece of paper towel first then tape.

I had some of that happen as well with 01. I had to use scotch brite pad to get it off which works fine since I like satin finish :)

You were forcing a patina and did not even know it ;)
 
I've been thinking about the haziness of the Tru_Oil. I'm going to try applying another coat, and just rub it in as I apply it, making a thin coat. That might be sufficient to get the satin luster, without having to buff it in any way.
 
I can't help with the wood finish as I have no experience with your process. Although I don't do it any more because of the residue, I used to put masking tape directly on my blades and found that the only thing that would get the residue off was lacquer thinner. Acetone or alcohol would not touch it. Now, those were all stainless blades so I really don't know if there is a possibility there could be some etching from the tape on your 01. For the future, Stan is right about not using tape directly on blades if you wish to avoid stuff like this.

Now that I think about it, the times I have gotten the patina under the masking tape, is times when I was wet sanding the handle. In other words, I think it is a combination of the masking tape, and the water seeping under the tape.
 
Let me make sure I understand you. The TruOil finish was TOO shiny and you want to make it less so? Maybe try the Water Lox satin finish? According to their web site it "Produces a satin sheen appearance (20°-25° gloss level)" I don't know what a 20°-25° gloss level is but their high gloss product produces an 85° gloss level. I don't have personal experience with Water Lox but use TruOil a lot.

A good cleaning with lacquer thinner or acetone, followed by a quick rub with Flitz will remove the stains from the blade.

I really like the 3M sanding sheets for handle finishing. They come in a color coded pack of six grits, from 400 to 8000. They are cloth like and last a very long time. You can do anything from a nice matte finish to a glossy polish with them.

TIP -
Take a marker and put an "X" on the back side of the sheets, as it is hard to tell the front from the back once used.
Store the sheets in a large Zip-lok bag and use until they are shredded.
 
Is that olive on the handle? If so I can feel your pain. I can get a great finish on about any wood I use but I struggle with olive. I'm just never really happy with it.

No, the masking tape will do that even dry, just left on the blade for a time, even a short one. Do like Stan said and wrap with a paper towel and then masking tape.

That's good to know. It is olive, and this is the first time i have used olive.
 
Yep I've just about stopped using it. I have a little left. Maybe somebody with more experience can help us both. I really like the wood just not the finish I've ever achieved and I've tried a lot of different ways.
