The BFM1A1 is a pocket knife with the typical design of Extrema Ratio. It is unique that a number of additional functions found a place within this knife. You always carry a can opener, bottle opener and screw driver with this knife. Also an awl is not lacking. The blade and the tools (with the exception of the awl) are locked with a liner lock in unfolded condition. Because blade and tools of this knife are clear, the BFM1A1 seems to be a little less tactical. A black version is available.  
  


The pocket clip is mounted at the edge. When carrying the knife in a trousers pocket, it hardly shows above the edge.

Très bon  Couteau, malgré  un reproche  consequent, une lame vraiment trop petite...

Pour une utilisation quotidienne assez bon couteau
Lame très épaisse bon tranchant 
Clip ceinture à améliorer 


Is niet goedkoop maar is gewoonweg een fantastisch mesje. Ligt zowat perfect in de hand echt handig (en vlijmscherp). Heel tevreden met mijn aankoop. En, naar goede gewoonte, perfect service van K&T

Qualität und Service - Topp !
Sehr empfehlenswert !

C'est un couteau de poche parfait, un tranchant impressionnant, une lame assez courte solide, qui permet de se sortir de pratiquement toutes les situations grâce  à ses outils, pas trop lourd, pas trop imposant  c'est un compagnon idéal... Trop cher quand même

General information

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.

Weight

Dimensions & weight

value_steel_hardness

The hardness in Rockwell C for a knife is always according to the manufacturer's specifications. When a manufacturer specifies a value of 56-58HRC, for instance, we always note the highest value, i.e. 58HRC.

Lock

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

In terms of grind we are talking about how the complete blade thickness extends into the edge. Want to learn more about grinds? [Read all about grinds on knives](/en/ct/knife-grinds.htm).
