The knife on the left is a Bark River Canadian. It's a bit big for deer but has seen good service for moose and on caribou. The steel holds an edge better than the Russell below, esp for skinning which I find to be hard on any knife.
Inside a Yukon Mountain Caribou in 2010.
Here is the same knife after I had it re-shaped to approximate the Russell. It was big improvement over the original shape.
