I just purchased a BFC Red and Black
Sifu in the last week.
The knife is a great piece of cutlery! The Red G-10 is very nicely textured, The inside of the SS liners are practically mirror polished, the action is smooth yet tight, without any sort of slop or play. The lock has functioned flawlessly . I will admit I will
not ever test my knives as roughly as some users on these forums, as I tend to baby my knives a little. I use them all as intended, but I treat them sort of like spoiled children in between uses. I would tend to believe that if you purchased a Sifu, you would be very pleased with the product that you recieve. I think that 1SKS still has some of the limited run red ones if the color appeals to you. Good Luck. Buy One, You will love it.
