I'm sorry if this topic has been covered already but in an initial search, I did not see any one single thread, so here goes.
I'd like to get everyone's feedback on testing the sharpness of a knife. I've seen those paper cutting machines and all that but I want to know about a non-edge-damaging at home by hand method.
The ones I know:
Dropped grape tomato on blade facing up at 12 inches. Should cut and hold tomato.
M. Carters three finger on blade slide (least that's where I learned it).
Arm hair shave in the direction of the hair
Paper shave--I feel this damages the edge I just crated
Finger nail slide--this gives me the chills and large gouges in my finger nails.
I'd really like to hear from the guys that are actually hand forging blades. I have to believe that you have a favorite tested edge sharpness test?
