Hattrig27: You have a nice barong that i think would date from early 1900s
to about 1930 at the latest. The punto is probably silver. I usually use wet
and dry sandpaper, starting at 180 and going up to 600. If you are really
ambitious you can go up to 1200. After degreasing blade with acetone i use
phosphoric acid,which is metal etch. I get it at Home Depot, and i use it right out of the bottle. It dosen't need to be diluted at all, at least that has
been my experence. It's best to do this in bright sunlight as it is a lot easier
to see the pattern develop. when you are through rinse the blade in hot
water and then use baking soda to nutralize the acid. Wash the blade again
in hot water, and then oil thoroughly. Hope this works for you.......Dave
