    I've used the same DMT hones for 20+ years without seeing any signs of wear. Don't use excessive pressure and clean the swarf off when they get loaded up (BreakFree does an excellent job of cleaning).

    Twenty years? I wouldn’t be able to go twenty years, much less ten. Maybe five ;) . The itch to pick up something shiny and new when the existing is perfectly fine is a noted character flaw of mine :)

    I have DMT diamond stone that are over 30 years old and working fine.
    Light pressure and lub with mineral oil.

    One XXC I did trash with attempt to flatten a bottom on old Stanley wood working plane, the soft cast iron and too much pressure (impatient) did tear out the diamonds from the nickel plating. The XXC is still working however, rather poorly.

    Hardened steel and proper pressure, let the diamonds to the work and they will last for many years.

    The early posts referring to Edge Pro are most likely from excessive pressure and/or poor quality imported diamond hones.

    Regards,
    FK
