  1. The UltimateReview by
    Another late review by me! Sorry! Totally agree with the previous reviews. This is my Number 1 go-to knife, wether it's for work in some remote location or for chopping down a tree in my back garden, or digging out a brick from a wall (sorry but I didn't have a chisel to hand!). I have yet to find a more robust, easy to handle yet precise knife either as a workhorse for strong, or delicate work. And I have bought and tried a lot.
    My version has the geometric camouflaged blade but that just makes it look pretty!
    HH, thank you as ever.

  2. FULCRUM Review by
    JUNE - 2016, Extrema Ratio currently have 7 bayonets in production, all based on the Fulcrum. This full size model is without a doubt their strongest fixed-blade. The 7" blade has a wide polished bevel. The balance point is just in front of the hilt. This is quite simply a beautiful fixed-blade, and a pleasure to own. The top quality scabbard has a click-fit hard insert, and a double snap retaining strap. Thanks to HH for a great price. I am very pleased with my purchase ! (Posted on )
