Not very practical for anything but fighting and then there seems to always be a controversy about fighting knives ( sorta like firearms).. I don't doubt there is good and 'not so good' regarding characteristics and features of tools in the fighting knife world, but skills / training weigh so much more heavily with knives.. so few people have any mentionable knife fighting training or experience. The Colt pistol was the great equalizer because someone with relatively little skill could end a fight with it..
Post led me to reading on this again- Heres' a cool site.

I have Fairbairn's Fighting book somewhere on the shelf.. need to dust it off and give it another read.
I have wanted a Gerber MkII since I was a kid in the 80's .. I see them on ebay periodically and get tempted...
I have my original one from the 80's. It's a beautiful thing.
