If you like 'em, get 'em while you can.
Shaving as preparation for surgical procedures is certainly going to become less and less common. It turns out that for many procedures, shaving the skin before the first incision actually increases the risk of post-operative infection; many hospitals now do not allow their surgeons to shave the skin prior to surgery even if they WANT to.
When all the hospitals have outlawed pre-op shaving, I doubt whoever makes these blades will continue to do so, because they will no longer have a market.
I have heard this as well,some surgeons have been using an oster classic 76 loaded with a 00000 blade , and this seems not to abraid the skin
