Edge Retention/Rolling Test Stand

[Bud]

Don't disagree Grepper that 55-61 may be a sweet spot for edge retention but only the lower Rockwells in that range are a sweet spot for price. You can buy Rockwell 55 everyday for $35.00 and maybe less but  every 61 knife i can find is at least $80.00 and some, like the Shun, are $180.00. I agree that tests at higher beginning sharpness levels will be very interesting. Like I said, this is just great stuff in my opinion.
