Definitely a different market for knives than what most of the makers who seem to hang around here cater to. From what I've seen, most of the knifemakers/"knifemakers" on Etsy sell very crude looking forged knives, "zombie apocalypse" themed knives, or are trying to pass off the Pakistani damascus specials off as their own. Consumers there generally aren't the typical knife-buying folk, so they're just looking for something that looks different than what they're used to. They're more likely to buy into gaudy embellishments and buy into catchy wording/descriptions than notice an actual quality knife. A lot of the knives that sell well on Etsy would get laughed off here.
Thus, I don't know many knifemakers who have had all that much success making sales from Etsy, so I wouldn't count on it for making sales (unless you get featured on the front page or build a following there, which is probably more trouble for you than it's worth). Too much crap for a buyer to sift through.
That said, it's a great site for other wares, and it is a decent alternative to Paypal and such to make and keep track of transactions, so it wouldn't hurt to list your items there. They charge a similar fee and are generally a decent site to deal with. I have a few friends who have had great success on that site with jewelry, furniture, clothing, etc.
