I have been waiting for a good deal on DMT Dia-Sharp continuous diamond sharpening stones for tool sharpening and waterstone flattening, maybe even knife sharpening. Recent (temporary?) price drops over at Amazon offer substantial savings on the 8-inch long fine and coarse grit stones. Additional stones may also be discounted, but these are the two I have been keeping an eye on.
