i recently picked up 2 1/4 grind blades, a Worcester and a Torrey. the Worcester has a slight smile to the blade. i have several hollow ground blades that i have no trouble honing to extreme sharpness, however the heavy grinds seem to elude me. i have a norton 220/1k and 4k/8k with a 15k finisher. i can clearly see the edge when i do a spot check under a light while honing, but when i go to shave, the edge just isn't sharp enough. is there a secret to putting an edge on the heavy grind, or is that just the nature of the blade?
