Kusanagi no Dynamito Katana

The Kusanagi no Dynamito Katana is the first in app purchase booster item in the game. Once bought, 8 extra slicing power will be added to your katana. More importantly, you will be given the ability to slice through Dynamite and Nuclear Cans. Once sliced through one of the explosives, your game will not be ended and you will not loose and information gained during that game. The dynamite or nuke will just split in half like the other fish, and fall back down the screen. This is a very useful item, you will basically be completely safe to slice all of your fish and treasures you caught underwater. The one downside is the price, $2.99 is a bit much, but the powers it allows are excelent.
