Reviews & Ratings for Extrema Ratio BF4 Contractor Linerlock Folding Knife — 1 review — Page 1

I first of all took the all black option for concealment. The double edges are razor sharp as are the matching serrations. The length is an actual length of OVER 4'' blade to truly act as a concealed dagger when presented open. The handling is fast. light but tough and the flipper system is smooth and fast. I really got excited over this as soon as I came across it and really favor it as a back up, out of the way knife. This is a great buy! Go for it! Semper Fi, God Bless! Cujo
