I have both the DMT 1200 and the Naniwa 1000. Both do a good job. The Naniwa takes a little longer but seems smoother, and the DMT seems to get the job done like NOW. It seems the key to setting the bevel is not to move off that stone, or diamond, until the full length of the blade is popping hair at its base. Don't move on until it does. Once you get that the rest is easy and your pyramid will work just fine.
