I've come to the time where the HHT, magic markers, magnifying glasses , etc are nice and may be useful if you're honing commercial. But, for me the shave is the real test. If after honing and stropping and the shave is poor. I just put that one aside and finish with another razor. I'll go back to the 'ruff' one and try it again ~2-3 times on a pasted strop or hone and if it still doesn't shave... A coating of grease and into the Resting Box to be brought out later after it has time to think about what it should do.
