Erik,

I've experienced what you're describing--sometimes a nice, sticky edge after stropping, sometimes a smoother one. If I don't get a sticky feeling, I'll do more stropping and try a few different techniques. For example, I might do 10 or 20 slower strokes with a little pressure, than 30 or 40 light, quick strokes. Lately I've been playing with letting my strop slacken just a tiny bit--maybe 1/2 inch or so in the middle.

If I settle for a less-than-sticky edge, I can usually tell during the shave.

Good luck,
Josh
