MF1 folding knife, thanks to its highly functional design and high performance, has earned a solid reputation in terms of reliability and robustness among professionals in the field.
Extrema Ratio bids now farewell to this historic and renowned knife with a final version that enhances its uniqueness: MF1 LAST CALL, a limited edition of only 120 pieces. Featuring a heat-treated to 58 HRC Böhler N690 steel blade with a drop profile, this folding knife is ready to prove its worth even in the most extreme situations.
One of the distinctive features of this model is the counter-screw to adjust the blade-fixing pivot screw. By removing the counter-screw it is possible to tighten or loosen the central pivot at will, so to obtain the desired opening fluidity. Simply relock the pivot with the counter-screw to secure the adjustment.
Featuring a burnished MIL-C-13924 finish, a glacial-inspired handle, and a reversible clip for a safe carry, MF1 LAST CALL is the collector's item you cannot miss.
It comes inside a waterproof and durable technical case with a metal plate bearing the progressive number within the limited series, emphasizing the exclusivity of the model.
MF1 LAST CALL is available and can be purchased exclusively on www.extremaratio.com (extremaratiousa.com for US citizens only).
