Not the least interested in knives from a collectors view but I do love and have need for a good tool. As I am out and about in the woods and in the archipelago, harvesting what goodies there are (game, fish, mushrooms, oysters, silence, etc) a quality knife is essential. I go for rugged, multi purpose bushcraft knives. Scandinavian "Scandi" cut/grind blade with a strong spine (to be able to whack it hard if needing to split something) and yet subtle and realtively small to be able to do some finer work also. Here in Scandinavia we have long tradition in making and using this kind of knife and I am faithful to the tradition - in using them.
As I have a couple of different environments I go to I use two knifes.
This is my forrest knife:
Casström Swedish forrest knife no 10, Sandvik 14C28N
Sea and archipelago knife:
EKA Nordic W11, Sandvik 12C27
An old ad for the Nordic line:
And of course you always need to carry a Leatherman tool when alone on an island.
Made my own "artsy" small blade during one weekend of knife smith course.
In short - I am not into knifes. But I could not live without.
