First impressions on the DMT ceramic: This thing is a beast. It's huge and the guards at the handle are equally monsterous. It really doesn't fit in my bag very well. I'll likely have to do a bit of modification to make it more travel friendly. It seems a lot rougher than the Mac, though. I know the Mac is supposed to be 1200 grit and the DMT is supposed to be 2000 grit, but it seems A LOT more aggressive. It may just need a bit of breaking in. I've considered taking a bit of wet dry to it in order to soften it a bit. I'm going to use it for a while and see how it settles in, but I caught a ten dollar off coupon at Cutlery and More last week and ordered a Mac. It was under fifteen dollars out of pocket, so it was a no brainer. If the DMT doesn't work out, I'll slot the Mac in it's place and all will be well with the world again.
