Yeah, I've got a couple of wedges but they're only recent arrivals - too soon for me to tell how long the edge lasts.

I wouldn't completely rule out stainless if I were you - I got a Henckels Friodur back in late Oct. last year, honed it in early Nov. and haven't needed to touch it since. I know that's not a particularly long time, but I do use it on average about 4-5 times a week, and on head stubble as well. Honing was a bit slower, that's all.

There's also stropping considerations - good stropping (I'm quoting theory here!) can keep an edge keen for a long while. In fact, I've read some members can keep an edge sharp for ages this way (but that's more than my stropping skills can replicate at this stage, so I can't give personal experience....).
