Over the last few years a new version of burrs has become all the rage, blind burrs and the thought behind this is not only a more cutting surface area, but also more effective cutting, that leads to a more consistent grind size distribution. But thats a lot of words, so thought it may be time to do dawn the lab coat once again, and do some tests to see if its real or rhetoric.
