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
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. Inevitably, the knives we most often use are the ones that are at hand in the kitchen. So why not create a set that, apart from being used every day, gives us the pleasure of just having it and is a decoration of our kitchen, or an exclusive addition to furniture?
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. Made of pleasant-to-care AEB-L stainless steel and an exclusive type of stabilized wood, i.e. 6000-year-certified bog oak, gives the whole a unique character. The included wooden magnetic stand helps in easy and hygienic use.

Sliwkosky Knives Modern Puukko Knife | Elmax | Black & Red G10 Leather & Kydex
Sliwkosky Knives Modern Puukko | Elmax | Black & Red G10 Leather & Kydex was inspired by Finnish puukko knives. Knifemaker Jakub Śliwka referred to a Scandinavian design, but made a knife from modern materials. "Modern" in the name also refers to the design itself, in which we can see the "game of angularity", visible especially on the steel guard. In this area, the individual planes of the steel take a different shade depending on the angle of the knife holding and the shadow falling on it. 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.

Sliwkosky Knives Nessy Knife | Sleipner | Green Canvas Micarta
Sliwkosky Knives Nessy Knife | Sleipner | Green Canvas Micarta is a powerful survival knife in the style of the nessmuk blade, known thanks to its popularization by the nineteenth-century American popularizer of life in the bosom of nature Georg "Nessmuk" Sears.

To achieve the desired effect, the knife uses Sleipner steel, known for its resistance to chipping and overload resistance. The size of the whole is 335 mm, with the shape of the blade itself and the profiling of the handle in a way that prevents the knife from slipping out of the hand of the whole, it even encourages you to work such as: clearing the area for the camp, baring wood, cutting trees, branches, etc.

Sliwkosky Knives Urban Bowie XL Premium Knife Elmax Carbon
Sliwkosky Knives Urban Bowie XL Premium knife was inspired by the design of knives from the bowie family. However, it is in vain to look for a detailed representation of the classic bowie in it, because the knifemaker Jakub Sliwka drew from the historical knife only a few characteristic elements specific to the blade profile. First of all, it modernized the size (the whole is 215 mm long), adjusting it to the needs of outdoor trips, where a large blade is not always needed. The result is a full-tang knife with a very universal purpose, in a classic, very nice design, which can be used with pleasure during a camping, travelling, in the forest, for food preparation etc. It will also not be afraid of planing, cutting medium-thick branches, or other activities that may need to be performed in the camp.
