Polish law does not restrict the carrying of knives. The Law on Arms and Ammunition only defines that it is prohibited to acquire, possess and dispose of "...blades concealed in objects that do not have the appearance of a weapon...". We are talking about blades hidden in an object that at first glance is not associated with a white weapon. Therefore, in Poland you can legally carry, for example, a spring knife, pocket knife, hunting knife, etc., regardless of its size. However, there are several situations in which carrying a knife is illegal. According to 50a § 1 of the Misdemeanor Code, one who carries a knife in a public place with the direct intention of using it for criminal purposes is subject to punishment. In such a situation, law enforcement authorities are required to prove that both prerequisites actually existed: possession of a knife and intent to commit a crime with a knife. It is also prohibited to possess a knife during the passage of an organized group of participants in a mass sports event (Article 50a § 1a). Thus, going to a game (or other sports event) with an organized group of fans who are traveling by train, subway or bus taking a knife with them is a misdemeanor.
