You are as skilled in the use of any tool or machine you've touched within the last hour as though you have practiced with it your entire life. The object itself will gain an increase in effectiveness, and never degrade when you use it (a sword gets sharper and never dulls, a shield gets more durable and never dents, etc)
History’s Weapon
You can glean the history of any object you wield, allowing you to recreate the feats of its past wielders. While you won't be able to copy their abilities, you'll still be able to imitate their skills and expertise. A sword that has slain countless enemies will allow you to cut through ranks of foes as if they were butter, albeit with some difficulty. A gun from a sharpshooter will allow your aim to improve to a near-perfect level, only missing on rare occasions. You hold an unparalleled understanding of your weapons, allowing you to wield them with ease and lethality.
