Well my only concern with purchasing the larger DMT is the $40-$50 more in price than the smaller DMT. Christ I dont even have $70 in all of my hones. I really didnt want to pay that much right now just to keep them maintained. For just cleaning and prepping the surface, does it really have to be the larger plate? Im sure it makes it easier, but it just seems a bit off to me to spend more on a lapping plate than I have in total on my actual honing stones.
