在规则中看到：
Q: Jack Krauser's ability to gain 1 knife weapon, how is this ability used?
A: Krauser's ability like any ability to gain a certain card is played as follows.
This ability can only be used if the player has 1+ of these said cards in their inventory or
discard pile. Once the ability is announced, that player may take the said card from his/her
inventory. If there is not one of the said cards in inventory, he/she may take one from the
discard pile. If none are available in any of these two situations, the ability can not be used.
那也就是说他的技能只能从自己的存货区或者弃牌堆里面找小刀咯？不能从资源区里面直接获得吧？
