When you first purchase a leather belt its not uncommon for it to be stiff and uncomfortable so you might need to soften it up a little bit rather than going through the potentially painful and lengthy process of breaking it in through regular wear. There are a couple of options you can try out to soften up that stiff leather. Rubbing your belt with either an alcohol solution or with some petroleum jelly, like Vaseline, can help as can treating your belt with a natural oil such as coconut, almond, olive, jojoba or almond oil. Leather is skin after all, and all skin benefits from being moisturized to make it softer and more supple. Rubbing any of these oils or a vaseline consistently into your belt is really going to help soften it up. Alternatively, you could also buy a dedicated leather conditioner or restorer, the kind of ointment that is commonly used to soften horse saddles and bridles, which again will do the job of both softening and polishing that leather tool belt of yours.\r
