Do you like compromises? (about knife design)
A belt knife- as perfect as possible
To cut bread, the blade must be at least 10 cm, probably around 15 cm to be functional
The blade shall not be longer then 10 cm, if longer, the blade feels to big for small type of work
A knife for woodwork shall not have longer blade then about 5-6 cm
An engraving knife works best if the blade is about 1 cm
A knife who is used to cut branches works best if the blade is about 20 cm long..or longer...
The blade must be thin when you slice onions or depart and skin small games
The blade must have a big belly to be able to put butter on the bread and to skin big games.
The blade must have a small belly and a sharp point to butcher fish during fishing
The knife must be light weighted so it is easy to carry long distances
But big an off to chop small branches for the campfire
And heavy an off to chop small trees when you need to build a shelter in bad weather
The handle
The handle shall be thin so the knife is nice and comfortable to carry in the belt
The handle must be big and wide to be functional and secure to handle in cold and wet weather
The edge shall always be razor sharp
Except when you depart fish, the edge shall slide along the ribs - and not hook up in the ribs
The steel shall be hard so that the edge holds for a long time
But not so hard that it brakes or is difficult to sharpen
The edge shall not collapse when the knife is used to open cans
But be soft an off to sharpen outdoors without hours of sharpening
It must be soft in the neck and have a hard edge
But then I cant use a hammer on the neck when I split wood
But I can hammer wire against a stone to cut off the wire
