Tactical medium folder with rear glass breaker, reversible clip and semi-assisted opening. Length blade: 9,2 cm

The **Extrema Ratio MF1** is a decent pocket knife, designed for military personnel. Solid, tough and powerful: that's the MF1 in a nutshell.

The blade is made from Böhler N690 steel. This is a very corrosion-resistant steel that retains its sharpness well. The MF1 is delivered razor-sharp, which is one of Extrema Ratio's trademarks. A glass breaker protrudes between the pocket clip. You can use this to effortlessly break car windows in the event of an emergency.

You open the MF1 with the thumb stud. A small part of the blade sticks out like a flipper, but that takes some practice and a good wrist movement. When opened a solid liner lock keeps the blade in place. Extrema Ratio has added an extra catch that can be used to secure the liner lock. There is also an extra kind of security built in around the pivot. This screw is knurled all the way round. The locking screw fits precisely into one of these knurls, meaning that the pivot can never be loosened unintentionally.

Très bonne impression de tranchant, solidité, style,prise en main 

mooi en goed in elkaar zittend mes het is een groot mes de staalsoort N690 is prima te slijpen wat ook de bedoeling is als je in het veld bent  wat ik persoonlijk wel O.K. vind. de prijs is wat hoog voor de staalsoort die ze gebruikt hebben als je naar andere hoogwaardige  messen merken kijkt maar je krijgt echt wel wat je verwacht als je dit mes koopt en dit merk . de linerlock mag wat robuster maar met de extra lock is deze prima, enige minpuntje is de pocket klip in mijn ogen door de constructie blijft deze vaak hangen aan de rand van je broekzak. maar ben er super tevreden over als ik hem gebruik top mes.
dank weer aan knives and tools voor de snelle levering. 

Couteau très beau et imposant. La qualité au rendez-vous et certes le prix est élevé mais c'est le cas avec tous les couteau de cette marque, donc je trouve que c'est un investissement qui en vaut la peine.

Prodotto davvero ben fatto, i coltelli di manifattura Italiana più apprezzati, metallo böhler N690 di Extrema Ratio resistentissimo e con una stroppatina torna a rasoio. Si presenta con una manicatura confortevole per lavori meno gravosi ma consiglio l'uso di guanti se si vuole impugnarlo ed usarlo all'inglese, il legno lo mangia come il burro e riguardo alla sicurezza ha doppia sicura sia liner-lock che con una levetta rossa posta sul lato affianco al liner-lock, l'ho usato per fare qualche picchetto, tagliato della corda del cartone e della plastica ma non ha perso l'affilatura e aggiustando un solo punto con lo strop è tornato a rasoio. Molto utile anche la punta frangivetro posta alla fine del manico. Che dire l'eccellenza un ottimo coltello tattico da salvataggio non esageratamente grande e tascabile con clip che lo rende a scomparsa nella tasca del pantalone o di uno zaino.

Zeer solide mes met een aluminium handgrip die zeer zacht en prettig aanvoelt in de hand. Nog nooit eerder zo’n grip meegemaakt en slipt niet weg uit je hand. Lemmet is tacticool, maar qua scherpheid had ik meer verwacht. Met een zwart lemmet is het oppassen met slijpen dus gebruik de juiste tools zoals work sharp. De flipper werkt goed en dat deze minder prominent aanwezig is vind ik een plus. De extra lock zorgt ervoor dat de liner lock combinatie niet zal falen. Het kost wat geld, maar zeker zijn geld waard voor een folder.

General information

We measure the sharpening angle ourselves. This value is the angle per side.  So 20º means that the total angle of the edge is 40º. Please note that knives are almost always sharpened by hand, even in factories. This value is therefore only an indication of a single tool measured by us. You are always free to choose your own sharpening angle. [Learn more about sharpening angles](/en/ct/sharpening-angles-explained.htm).

Sharpening angle

We always measure the blade height at the highest part of the blade.

Blade height

We always measure the blade length ourselves. This is the length of the blade from the tip to the front of the handle. This may deviate from the manufacturer's specification.

Blade length

value_blade_length_edge

The length of the cutting edge is measured from the tip to the start of the edge. This may deviate from the manufacturer's specification.

Cutting edge length

We always measure the blade thickness at the thickest part of the blade. Often just before the handle. This may deviate from the manufacturer's specification.

Blade thickness

value_closed_length

We always weigh a product as bare as possible. Knives and axes always without their sheath, lights (if possible) without their battery. For knife sets we measure the entire weight. This may deviate from the manufacturer's specifications.
