I find it confusing when ever someone says they are looking for a skinner. Years ago I did a lot of trapping, and a fair amount of hunting, to my mind a skinner should have a well rounded tip, this style of knife would be used for bear, beaver and such, the rounded blade being used for fleshing and skinning at the same time, the rounded tip saving you from making holes. The knife I liked for fox lynx and such was a slim blade with a sharp tip, the blade being about 2.5 inches long. a couple years ago I started making a knife a I call a detail knife, I made it specifically because there are so many people using the knives with the throw away blades which are quite brittle this knife was made for skinning bear toes, it works pretty well for splitting lips and turning ears and such, this has a very pointy profile, and short blade, like 1.25-1.5 inches long.
It seems like any knife anyone ever used to skin any type animal is called a skinning knife. most of what I see called skinners are what I would call a hunting knife not really a special purpose knife more of an all around tool you could use for skinning and field dressing an animal. A skilled person with a good hunting knife should be able to skin and field dress including cutting into packable sized loads a moose or elk or deer with out resharpening or using any other tool. Obviously if you had a saw or axe with you so much the better.
IMO the knife posted by the OP might be pretty fun to try, I would think it should work pretty well as a skinner, for field dressing large game or probably skinning beaver types, i would not like it as a capeing knife as I think I would have trouble skinning ears, and such I do not think it would work to well for skinning toes either as you would not be able to reach in the small area with the wide blade tip.
