Fallkniven F1 knife is used by the Swedish Airforce as a survival tool. This is a Swedish knife but not made in Sweden. The metal used is a VG10 steel which stands for V Gold 10 or sometimes known as V-Kin-10(V金10号) that are used in Japanese cutlery mostly the Chefs' Knives. In another words the Fallkniven knife is made in Japan.
Found a knock off sales below USD20 in China market and decided to get one and see for myself. The knife felt very good in my hand and the weight was just right to use for chopping. Did a search on the internet for the specification and surprising came across the Original and Copy specification.

The knife definitely felt good to use, it chop and feather the wood with ease, comparing with my Buck Selector it needed some effort maybe due to the weight of the knife. The knife at the thickest is 4.5mm not 3.5mm, not many knives of these size are made this thick which is good to use for hammering and strength, normally 3mm ~ 3.5mm thickness. The weight of the knife is 155gm.
The blade edge is definitely not convex, the original convex edge width is around 4mm, the copy is a 1mm V cut edge. The advantage of a convex edge is that it is really sharp but very difficult the maintain. You need to have some skill in sharpening a convex edge knife. The blade came sharp and slicing up paper was not a problem but there are still feel minor rough edge that still needs to straighten out. Normally using 600 and 2000 girt paper should be able to sharpen it.
As much as I know the knife can start a fire and chop down stuff, the material is not VG10 but for survival this knife can do the job. The weight simply felt good it is only the cutting edge from the original. If it still can cut...who really cares.
size comparison between the 25 years old original Buck Selector
Shank is thick enough for a whack to chop woods
yes the top blade can set a spark on a fire steel
The knife sheath was leather made, the construction looks pretty good just that the button flap felt it was in a way if need to draw the knife out. They do come in Zytel Sheath which I did not opt for, the leather sheath looks better in terms of concealment.
