All we got are the semi-annual Historic Arms show, they usually happen in March and September. Some knife shops are there, Chin from the Stadium Swap meet is always there, with some smokin' deals and Power Edge and Young Guns are usually there also.
Some local custom makers show up, Carl Zakabi and Stan Fujisaka are normally around, Ken Onion used to go, but I haven't seen him lately. Tom Mayo was there this past September, he had 3 nice Beefy-T's, too bad I couldn't afford one.
That's about it, IIRC, about 5 years ago there was talk about having an honest to God knife show here, there were even advertisements in Blade Magazine. Ultimately, it's just not economically feasible for knifemakers to fly themselves and their stock all the way here, find lodging and pay for a table at a knife show, and expect to turn a profit.
Anyway, keep checking the paper and Blaisdell Center's website around the end of February, there should be more information on the exact dates and times of the show.
