I don't know anything about the Artemis razor apart from what a quick google search told me:
- they are very cheap (generally a red flag)
- I was unable to locate any information regarding where they were made or by whom (a very big red flag)
So I suspect (but do not know) that the Artemis is one of any number of cheap - note cheap vs. inexpensive! - blades made possibly in China or Pakistan, stamped with 'Artemis' and sold to an unsuspecting public. I will certainly stand to be corrected if that is false, but that's the impression I got from my quick search.
Cheap blades should be avoided. However, inexpensive ones can be ok. For example, keep an eye on the classifieds here at SRP. You'll find plenty of good, shave-ready blades, often at very good prices.

Personally though, I would not waste any more time trying to get the Artemis to a shave-ready state.
Which raises another point: have you ever used a truly shave-ready razor? If not, how will you know when you do get a good edge on one? :) The best advice when starting out is to send *at least* your first razor to a pro to be honed, or to make sure you buy it in a shave-ready state. That way you'll get a feel for what you're aiming for when you are honing it yourself.
