If you don't mind buying from Cold Steel, and you are OK with Carbon V steel, you might take a look at their line of fixed blade knives.
Consider the following:
SRK (single edge, 6" blade, 3/16" thick, 8.2 oz.)
UWK (single edge, 6 1/2" blade, 3/16" thick, 7.8 oz.)
ODA (single edge, 7" blade, 3/16" thick, 8.7 oz.)
Recon Tanto (single edge, 7" blade, 3/16" thick, 9 oz.)
OSS (double edge, 8 1/4" blade, 3/16" thick, 9 oz.)
Recon Scout (single edge, 7 1/2" blade, 5/16" thick, 15 oz.)
Trail Master (single edge, 9 1/2" blade, 5/16" thick, 16.7 oz.)
I have only handled the Recon Tanto, but it was very sharp and seemed very well made.
