Very interesting thread.... I travel in both circles. You're right there are many areas that cross over.
I have seen the show raffles JCIN, and the flood to buy the blades right after they're done. People get a raffle ticket that "allows them to buy a blade at the price stated".... and then they flip it 10 mins later....
Here is my opinion on this....
1). Net presence is the future for both, not in person shows. (unless you refuse to buy without physically laying your hands on it first). There are less and less shows for blades... of course there is still Blade and the gathering etc, but in general its dwindling.
2). Raffles are successfully done ALL the TIME on various knife forums... Yes it allows folks to get a blade they normally couldn't afford, and / or wouldn't want to wait for, on a list.
3). Here is the primary difference IMO..... Knifemakers are willing to keep and maintain subforums to display their work. A lot of them do this instead of having a website of their own. They have these subforums where the customers are already present, looking for blades. Of course this wouldn't help cuemakers who have lifetime lists, (They already have enough work), but to me it would sure would be interesting to see. Facebook has a lot of this already too, but I still prefer the forums. One of the best is

Take a look at the pic below... This is from the Jerzee Devil.... and it gives you an idea of all the subforums for individual makers might look like. This is just a sample.... Lots of these guys show almost every step they take in their WIP threads.... And there is knives raffled off quite frequently...As a matter of fact there is a Halloween build off over on the Jerzee Devil that I am entered in, and I believe a lot of these blades will be raffled off, after it is over...
