i have Dmt 1200 and 8000. i have used dmt 1200 a lot lately and recently find out my 1200 dmt is acting similar to 8000k?
Now i do understand because of a lot use it will loose diamonds slowly and sharpening quality will go down. What i don' t understand is this why it does fine job same as 8000k. diamonds should be larger size and always must leave deeper and larger scratch marks then dmt 8000.
Is anyone else has similar experience?
what do you guys think?

Both plates has been brake in before starting use. i use 8000 very rare
Suggestions welcome
