I own a Gigand Titan which I've found to be a serviceable knife for the price. It's essentially a United Fred Carter FC5, although the blade steel is AUS-8 instead of 440 (440A?). When I bought it for about $35, it sold for about $20 less than the United version.
Since I liked my Titan so much -- with the exception of the pocket clip which makes the knife ride very high in the pocket -- I did a little research on the Gigand line. From what I recall, United initially produced the Fred Carter knives, but Gigand later bought the rights and tooling to continue producing them. I think I found that info here at Bladeforums. It seems that United is still selling the Fred Carter designed Harley Davidson knives though.
I'm not sure if Gigand really has gone under since their website is up and running, as opposed to it being down for a very long time between six months and a year ago. The only place on the web that I've found Gigand products is Blowoutknives.net (whose site is essentially down since only the homepage will load) and Knifecenter.com. Maybe the folks at 1SKS could look into retailing the Gigand line?
I hope this helps.
