Bark River Knives has a forum of similar character to the ESEE one:
http://www.knifeforums.com/forums/showforum.php?fid/59/
I frequently read (post a little) in both and the same quality discussion takes place over there. Drop in and take a look to learn more about BRKT knives if you have not had the pleasure of knowing much about them.
I have a RC-3 and an Izula and like them a lot but I bought a BRKT Liten Bror in 3V steel a few months back and it came out of the box light sabre sharp - seriously!! I have never handled a knife that sharp before - gave me a new baseline for "scary sharp".
BKRT has a very similar warranty and repair policy to ESEE so no worries there.
While ESEE has a smaller product line with only a few variations (colors, handles, etc.) you can get BRKT knives a huge range of styles, designs, steels, and handle materials. So you can really find something that fits your personal use needs and preferences. They typically only make their models in batches so if you miss the design you are looking for you might have to wait until the next batch is produced if it is produced at all again (happens to some of the less popular models).
I am a fan of convex sharpening and all BKRT knives that I know of are hand convexed from the factory.
Like ESEE, BRKT seems to value their customers to a high degree and participates in the forums to engage their customers in discussion on a daily basis.
BRKT knives are very dangerous knives to get interested. With so many models and varieties, you could very quickly drain your bank account. This is a VERY bad thing if you are easily tempted to buy quality knives you know you do not need (so far I have resisted buying any more - but it has been difficult

)
