&amp;#039;&amp;#039;Z-12 Ultra BQ is a “blade-quality” expression of Zapp’s Z-12Ultra PM™, an ultra-wear-resistant steel developed specifically for high-volume industrial tooling applications. That steel’s proprietary alloy composition provides significantly enhanced wear resistance, toughness, and compressive strength compared to common high-wear tool steels. Z-12Ultra BQ optimizes that steel’s properties specifically for use in knife blades and is a proud member of Zapp’s elite BQ family of cutlery steels. &amp;#039;&amp;#039;&amp;lt;ref name=&amp;quot;Mule Team MT45P&amp;quot;&amp;gt;Z-12 Ultra BQ information in [https://spyderco.com/products/mule-team%E2%84%A2-z-12ultra-bq%E2%84%A2 Spyderco&amp;#039;s online catalog, accessed 12 November 2025]&amp;lt;/ref&amp;gt;&lt;br /&gt;
