All About Pocket Knives

I finally got my first vintage knife, a Boker Tree Brand 449, and there is white tape on it. I tried Hydrogen peroxide, and nothing.

ooooooh, a 449. I don't have that one in my database. Got any pictures to share?
As for the tape, a small amount of mineral spirits, rubbed on gently with a clean cloth, should be enough to remove the tape residue.

Before you try the advice above, What is the handle material? If bone, proceed. If celluloid, don't do nuthin'!!! (perhaps a gentle soap, and COLD water)

Ill take a picture in a few, what is its value? Its material color is a red/yellow. I hope that since there is about 3/8's of the blade missing it wont its value too much.

I use Goo Gone.
I have not had any problem with it hurting the handles.

Tea Tree Oil or Eucalyptus Oil is good to remove any stickies or chewing gum things.

It pays to be a little cautious when using Tea Tree Oil (this is the first time I've heard of Tea Tree Oil). A little research found the following. Wikipedia, of course. http://en.wikipedia.org/wiki/Tea_tree_oil

According to the American Cancer Society: "Tea tree oil is toxic when swallowed. It has been reported to cause drowsiness, confusion, hallucinations, coma, unsteadiness, weakness, vomiting, diarrhea, stomach upset, blood cell abnormalities, and severe rashes. It should be kept away from pets and children."

A small number of people experience allergic contact dermatitis as a reaction to dermal contact with tea tree oil. In an Italian study of 725 consecutive patients, patients were patch tested with undiluted, 1%, and 0.1% tea tree oil. For undiluted tea tree oil, nearly 6% of the patients observed positive reactions of skin irritation. Only 1 of 725 patients observed a positive reaction of skin irritation with the 1% dilution. None of the 725 patients observed adverse reactions with the 0.1% dilution. Allergic reactions may be due to the various oxidation products that are formed by exposure of the oil to light and/or air

If you use any of the above things to remove tape residue for a prolong amount of time "like every day eight hours a day" You will probably get health problems or even cancer.
Wear rubber gloves and a respirator if you handle chemicals all the time.
But a little every once and a while won't hurt you.

Sometimes peanut butter works...similar to mineral oil...

Not bad mouthing Goo Gone. Just posting a list of the ingredients, taken from the MSDS (Material Safety Data Sheet)

Sometimes you don't have to buy the brand name product to get the results.
