I also only have one fixed blade, so I guess I should expand there too.
Rather than polluting the forum with bad photography, here's a link to my fixed blade photo:

I also took a seperate photo of my bayonets, but it didn't turn out well at all. Based on your knife choices so far, I think you'd like the Buck Nighthawk and perhaps the C.R.K.T. Stiff KISS.
I recently bought my first Axis, a Benchmark Griptillian. I was a bit dissappointed with the handle material, but the lock is cool.
I think you'd like the AG Russell Featherlite One-Hand Knife, available in ATS-34, or the less expensive AUS-8.
Believe it or not, my collection has cost $776.
I tend to bargain shop, looking for closeouts, specials, and inexpensive knives of good quality. I do stay clear of totally cheap crap, although as you can tell from the picture a few have snuck in there by way of gifts or freebees. "You collect knives? I found this in the back of my truck last month. Want it?" Notice the Velveta box of junkers in the back?
Perhaps after I cover that field, on to bigger and better things like high end production and customs.
I've recently began to shop for customs, staying on the inexpensive side. Anza knives custom designed and created a knife based on my ideas and using my choice of materials. Very reasonably priced and mailed in five days. You should check out their website.
But for now I kind of just want large variety.
As you can tell, I love variety. I certainly wouldn't want to limit myself by buying a single brand or style of knife. A few things noticably absent from your collection: traditional slipjoint, traditional American-style hunting knife, Scandanavian-style hunting knife, an OldTimer, a military bayonet, and anything vintage.
Noticably absent from my photo, a multi-tool. There is one, but it's a Chinese piece of crap that someone gave me. I like the SOG multi-tools with the gear-driven pliars but haven't bought one yet. Have you seen those?
Best Wishes,
Bob
