### ⭐⭐⭐ Bin nicht wirklich begeistert :(
*by A***E on 7 January 2021*

ich besitze alle DMT mini schleifsteine und bin sehr zufrieden mit denen, aber DMT gibt selber an das seine produkte stärker mit diamanten bestück sind als andere hersteller was bei diesem produckt nicht gegeben ist da man die diamanten schon glatt abzählen kann und die hälfte davon schon abgebrochen ist weil ich habtsächlich messer mit scandi schliff habe kan ich den kaum oder garnicht verwenden, aber für messer mit einem normal schliff ganz OK auch wen ich die lebenserwartung etwas anzweifel
