Use your Hunter's Hammer to smash various items into smaller parts!
This Crafting tab option can be used to smash certain items for use in crafting other items. The in-game Hunter's Hammer Crafting page lists items that can be smashed or dismantled, along with the quantity of each item owned. A hunter can select the quantity to smash, then hit the Smash button, which pops up a window. The window asks Are you sure you want to smash item? as well as listing the parts that will be obtained from smashing.
If the item being smashed is currently in use as a Weapon or Base, the hunter is given an error message: "Sorry, you can not destroy your last equipped trap". To smash that item, it is necessary to first equip a different trap.
Many smashed items can be reassembled, but sometimes the reassembly requires extra ingredients (for example, Curds and Whey for SUPER|brie+). However, there are some items where smashing is a one-way conversion (for example, High Tension Spring).
Smashing a Library Assignment will allow you to select a new assignment, although you will be unable to start a new assignment for one hour, starting from the time the previous assignment was assigned.

Move along, nothing to see here!
In the special case of a Library Assignment, using the Hunter's Hammer produces Nothing. This item in the Special category is then immediately removed from the hunter's inventory. In other words, all hunters always have 0 instances of this item, and it does not show up in normal inventory listings.
