…in the royal marines corps... extrema ratio was the choice if own items were used…
I had to do a little research to find out what this Extrema Ratio was. I found that the knife’s blade steel is N690 cobalt stainless steel (I have to admit I don’t really know what N690…means, but it sounds cool.) It has a new sheath design that allows for 45 degree as well as horizontal and perpendicular adjustable carry positions. AND it looks really cool!
