Ashima "hot potato"

Class

Improvised weapon. Generally but not exclusively made from TNT used in mining/demolitions. Delay in explosion is controlled by a burning fuse.

Variations can include radio command wired into a blasting cap, or hardwired into a specific target.

Size

Dependent amount of explosive used,  typical length 203 mm diameter of 76 mm. Mass is around 2-3 Kg.

Cost 

50 Credits of dynamite will generally provide sufficient quantity for a few blasts.

Rarity

Common. Anywhere that is on a land trade route with a mining settlement will probably have a regular supply of the required components.

Damage

High explosive damage consistent with a H.E. hand grenade. Variants coated in adhesive materials and metal components will do additional shrapnel damage.

Complexity

Preparing a charge requires simple tooling and minimal consumable equipment, Setting a reliable fuse time does not require complex knowledge of high explosives, but a person with specific training and expertise will be able to recognise poor quality components and potentially flawed explosives.
