Cutting, sawing, scraping, digging, hammering... all that is possible with that oldschool, huge piece of diving-metal.
It is so big and sturdy, you can even use it as a crowbar to break things open. Just remember to rinse and grease it regularly and it will serve you decades.
HINT: Replace the rubber retaining loop with one made of bungee-cord. It will hold longer and keep your knife from getting lost.
