Sliwkosky Knives
“My knives are a promise”
Sliwkosky Knives: Jakub Sliwka, a Polish knifemaker with over a decade of experience, has been professionally crafting knives since 2018. His journey into knifemaking began early, driven by his technical talent and a DIY inclination noticed during his youth. Additionally, his interest in the knife industry played a significant role. These elements converged to establish Sliwkosky Knives, a project named after the knifemaker (sliwka = plum). Before its inception, several years were dedicated to acquiring knowledge, honing knifemaking skills, and participating in industry events.
While Jakub Sliwka earned an engineering degree in a field less related to knives, it provided valuable insights into technical processes and planning. Returning to Sliwkosky Knives, the name and plum-shaped logo evolved over time, symbolizing noticeable individualism present in each project—original creations inspired by designs from various countries and cultures.
This influence is evident in projects like the Bushcraft knife (stylized as a Custom Mora), drawing inspiration from popular Swedish knives, and others such as Urban Bowie, Modern Puukko, Kukri, or Kwaiken. Despite diverse inspirations from Scandinavia, the Far East, or America, common details characteristic of Jakub Sliwka’s work are evident.
Sliwkosky Knives now focuses on crafting knives from premium materials, including Elmax, M390, Vanadis 4 Extra, Sleipner, D2, and AEB-L steel. The blades undergo meticulous self-hardening, and the handles are typically crafted from durable materials like Micarta, G10 composite, carbon fiber, or stabilized wood. Kydex and occasionally natural leather are used for holsters, with the latter recommended when it complements the knife’s style.
The Sliwkosky Knives lineup includes knives for everyday use, outdoor activities, bushcraft, survival, hunting, and kitchen use. As Jakub Sliwka states, “My knives are a promise,” emphasizing his commitment to delivering reliable and high-standard knives that bring satisfaction to the clients.

Sliwkosky Knives Kitchen Knives Set 6 PCS | AEB-L & Bog Oak was created from the need to have high-class kitchen utensils with unique features and the nature of handcrafted production.

Sliwkosky Knives (Jakub Sliwka) decided to meet this task and the result of his work is a set of 6 knives, different in size and target use.

It is only an illusion, but it gives a very unusual and exclusive effect. The whole project looks very aesthetic and elegant and is emphasized even more by the quality and precision of workmanship.
