It is no surprise that the laps made in China are more diamond-loaded. China is an aggressive and serious producer of HPHT synthetic diamond. The prices really crashed from when they were being made here. We more or less screwed ourselves more than ten years ago when the EPA established hefty fines for the improper disposal of Watts or Electroless Nickel plating solutions. My company and many others either shut down their Nickel plating lines, or offshored the plating to places that could dump it in the river. The Chemistry is the same no matter where it is made.
Usually plated laps should be considered disposable. When new, tey are very aggressive, and have ocassional rogue diamonds that get loose and scratch. Then they quiet down and are very good products. At the end of their lives, the nickel is eroded by swarf, and they begin to lose diamond, and the diamond has dulled as well. When they get this way, remember how little you paid for it, and discard it. There’s no such thing as a “well-worn” lap. If it’s worn it’s not “Well”. It’s terminally ill. H ave you ever seen a “Well-dull” knife?
