Ok so I've been shaving with a straight for only a little while. I am nowhere near the magic 100 shaves, but I have gotten to the point where I can shave my entire face although it takes a long time is not super close yet. But I'm running into a consistent problem. I can't keep my blade sharp for even one entire shave. I test my blades (I have 2 -- a gold dollar from Buca on this site and a starter from Larry at Whipped Dog), by doing the "tree top" test on some arm hair. I can tell my blade will be sharp enough if it easily catches and cuts arm hair. However, after a shave it won't do that anymore. Even if I stop 40+ times it never gets that sharp again unless I do about 5-6 laps on an old barber hone that I picked up from eBay. However, everything I read says that I should be able to keep my edge shave ready for at least 15 or so shaves with just stropping. I can always get it back to nice and sharp with barber hone, followed by 20 laps on green CrOx, 20 on red CrOx (from whipped dog) then about 40+ on the strop. Super sharp and buttery smooth after this process for about 1/2 a shave --what's up? Is it possible that my tough beard is dulling the blade? Is it a technique thing whereby I'm using too much pressure? Why can't I bring the edge back after a shave with stropping? Do my razors just suck and do better ones have more durable edges? Any advice from more experienced folks would be helpful. Thanks.
