I recently cleaned a bunch of rusted screwdriver bits by soaking in cola overnight. They only needed a mild brushing with steel wool after that. If I was trying any other restoration work on metal I would use it again. I often restore knives and tools so the cola is a real time saver.
 i found an old knife with a bone handle and im going to try this
That's great, good luck whith the work.<br />
thats a sweet knife excelent buy
Thanks, for the commentary.
Great pictures! You may have cleaned it to much, by removing the patina you have removed much of the value but knife collectors will still go wild over it.<br /> &nbsp;I hope this translates properly
OK, it were very rusted, thanks for the aid. Sorry about my english. :-(<br />
in this case it was more rusted than age patina so you had no real choice and you gave a relic new life.<br /> &nbsp;Your english is better than my german or spanish, I only speak a few words or phrases in each
Neat Knife. DRGM means it was made in Nazi Germany, if you weren't aware.<br />
Thanks a lot for the information
