I bought an old Morso 8900 that came with two sets of blades. I have been exploring their dimensions using a granite surface plate feeler gauges and a dial indicator. I was puzzled to find the back side of the blade (the flat part that you are told not to touch other than burr removal) was quite hight in the middle when lying on the flat surface. I can easily get a .003 feeler under there. There seems to be some lore around these blades; I know I could lap the back very flat on my surface stone but I have read a lot of comments that say do not touch the back you will ruin the blade.
Are my blades good? Are they sprung a bit?
thanks in advance
