Has anyone used the DMT DuoSharp Plus stones? I'm wondering how the continuous part on the end works out, particularly when sharpening a chisel, and if it really makes that much difference in sharpening small and pointed tools. Much thanks for any info!

Hi all, I'm new to this forum, I'm about to acquire a stone engraving cnc router and would like to know if someone on this forum has experience with GMCNC and Jinan Fine technology JINAN FINE TECHNOLOGY CO.,LTD from China, reliability, support,... Regards.
