The larger version of the Extrema Ratio T4000, this tanto blade is the perfect size for heavier-duty jobs. You'll want to grab this knife when you've got serious work to do! The tanto is not only supremely cool, it's wonderfully practical. The shape makes for a hyper-strong blade, great at stabbing and puncturing without breaking. This knife is a beast, with a large and comfortable handle that has great grip, and then there's its workhorse of a full tang. The lanyard/glass breaker is an added convenience we really appreciate.
