The popular and classic Tsunami knife hasn't just been reintroduced, SOG took what made the Tsunami so great and improved it. Some of the changes are subtle, like refining the overall balance, while others are more obvious, like the grooves in our crossguards. The Tsunami's tanto style blade shape is mated perfectly with an extremely tactile diamond checkered Kraton handle. The Tsunami comes with a MOLLE compatible nylon sheath.
