- Grenades are largely divided between the 'fuse' and the 'body'
- The 'body' determines the effect of the grenade, while the 'fuse' determines the timer of the grenade.Delayed FuseStrikerExplosive FillingTungsten cube fragmentsSafety Pin, Safety ClipSafety LeverExplosive bodyDetonator

The safety pin is rather difficult to pull out, so I do not recommend that you bite it and try to pull it out with your teeth, Sensei.
