The Tough Glove is a weapon item found within the first Dimensional Box the protagonist comes across in Snowdin Forest. It is also purchasable from the Snowdin Shopkeeper. Its defensive counterpart is the Manly Bandanna.
Its attack animation is merely a bunch of small fists every time the player presses the Z key, which varies between 1-4 fists. This, in turn, causes one big shockwave that damages the enemy.
