I’ve owned my share of customs and evaluate every tiny nuance on every piece of gear I own. When it comes to processing game the pinnacle IMO is this little semi skinner from Dan Crotts. The blade shape, size and angle relative to the handle is perfect for gutting, skinning and if needed deboning. I’ve never lost an edge in a season with his D2 and by not lose an edge I mean it’ll still shave effortlessly. The most I processed with it in a year between sharpening was a bear, three elk and six deer and it still pillowed hair off my arm.
You can pick it up in micarta for a shade over $200
It was so perfect I had it built the way I wanted and it’s performance outperforms it’s beauty.
Now if you want something without the wait the next best would be a dozier Yukon pro skinner. It’s got the edge retention in spades but the blade shape isn’t quite as perfect as the little semi skinner IMO. It’s still very, very good and can be had in micarta for about $220.
The only maker (I’ve owned) who I feel makes higher performing knives is Phil Wilson. I love his filleting knives but his hunting designs don’t have the blade shape I desire so I don’t own any.
