One of the most popular materials for professionals and enthusiasts is steel <strong>N690Co<\/strong>.

It is characterized by a high carbon content and the addition of cobalt, which significantly improves its mechanical properties and corrosion resistance. Thanks to these characteristics, knives made from this steel are extremely durable and reliable in harsh off-road conditions.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Wlasciwosci_techniczne\"><\/span>Technical specifications<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Hardness:<\/strong> After appropriate heat treatment, N690Co steel reaches a hardness in the range of 59-61 HRC, which provides excellent focus retention.<\/li>\n\n\n\n<li><strong>Corrosion resistance:<\/strong> Due to its high chromium and cobalt content, this steel is exceptionally resistant to moisture and other atmospheric factors.<\/li>\n\n\n\n<li><strong>Easy sharpening:<\/strong> Despite its high hardness, N690Co steel is relatively easy to sharpen, which is important in the field.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Testy_wytrzymalosciowe\"><\/span>Endurance tests<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>In the book \"Choose His Knife\", the author gives a number of strength tests that confirm the excellent properties of N690Co steel:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Cutting a climbing rope:<\/strong> 200 times without the need for sharpening.<\/li>\n\n\n\n<li><strong>Cutting a 35 mm wide strip:<\/strong> 200 times without losing focus.<\/li>\n\n\n\n<li><strong>Cutting Beech wood with a diameter of 18 mm:<\/strong> 150 times in machete mode.<\/li>\n\n\n\n<li><strong>Wood drilling:<\/strong> 10 times with an 18 mm drill bit.<\/li>\n\n\n\n<li><strong>Drilling in kevlar:<\/strong> 10 times at a certain energy.<\/li>\n\n\n\n<li><strong>Concertina type barbed wire cutting:<\/strong> more than 100 times.<\/li>\n<\/ul>\n\n\n\n<p>These tests confirm that N690Co steel is capable of solving the most complex field tasks.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Zastosowanie_w_nozach_mysliwskich\"><\/span>Application in hunting knives<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Due to its properties, N690Co steel is an ideal choice for making hunting knives.
