Etsy has a pretty decent learning curve to get your listings to show up at the top with the keywords you want. Generally those keywords are the same that "the other guys" also want to be seen under. "The Other Guys" are generally the garbage knife makers that are selling for $30 and less.
When you start diving into optimizing your pages, etc. These tools can help:
www.erank.com ,
www.etsygadget.com . They can teach you about "long tail" keywords, competition, etc. It gets pretty in depth and can be important if you want your listings in the top 10 pages. Watch getting pushed into offering free shipping unless you add that cost to your knife. You'll notice many offer free shipping and I believe your ranking can be lowered by etsy if you don't offer free shipping. At least that used to be the deal.
I've got a store but I don't do much with it. Mainly because of the amount of junk on there.
