Ok, I'll now give you the straight skinny on this. At first after 6 shaves I stropped the blade usually 15-30 times on canvas and leather and thusly gained 6 more good shaves. Then again after 12 shaves I did the same stropping procedure and gained 6 more good, close shaves. Then stropping again after 18 gave me only 2 good shaves before requiring some stropping. Now, I'm about to use it for shave #22 and it will probably require some stropping afterwards. I'm sure it will follow this pattern a few shaves before dropping to needing a stropping after each shave which I'll not continue to give. Yet, what I've done is determined how long a DE blade can go with little maintenance while delivering good shaves. This seems to be right around 20. I'll take mine a few more shaves in order to finish out a full 2 months worth of shaving, '24' shaves. Since I was sailing uncharted waters here as no one else has done this, I learned some things along the way and enjoyed this effort. By the way this amount of shaves brought the cost down to about .01 per shave and I'd only use 6 blades a year. DM
