Sold without handles or sheaths, Mule Team blades are also ideal for aspiring knifemakers and hobbyists.\u003c\/p\u003e\n\u003cp\u003eThis expression of the Mule Team concept features Crucible® CPM® 4V® blade steel—a powder metallurgy tool steel that offers high impact toughness and very good wear resistance. Developed for demanding industrial applications where a combination of strength, wear resistance, and toughness is required, CPM 4V has significantly more carbon, vanadium, and molybdenum than CPM 3V®. The result is a steel that is capable of a higher attainable hardness and even greater abrasion resistance than CPM 3V and significantly better toughness and wear resistance than D2. Despite these advanced performance qualities, CPM 4V has only 5% chromium--below the threshold of stainless steel--and therefore must be properly maintained to protect it from corrosion.\u003c\/p\u003e\n\u003cp\u003eLike conventional steels, particle metallurgy steels begin with a homogeneous bath of molten high-alloy steel. However, instead of being poured into ingot molds, the molten steel is forced through a nozzle under high pressure to create a spray of small spherical droplets that quickly solidify into powder particles. The small size of the particles forms micro-ingots, drastically reducing the alloy segregation in the steel and ensuring an extremely fine, uniform carbide structure. This enhances the steel’s edge retention, as well as its grinding and polishing characteristics.\u003c\/p\u003e\n\u003cp\u003eCPM 4V's exact alloy composition is as follows: Carbon: 1.35%, Manganese: 0.40%, Silicon: 0.80%, Chromium: 5.0%, Molybdenum: 2.95%, Vanadium: 3.85%.\u003c\/p\u003e\n\u003cp\u003eAll Mule Team blades are sold consumer-direct and available only at the Spyderco Factory Outlet or through Spyderco.com. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eReleased: October 2015\u003c\/strong\u003e\u003c\/p\u003e","brand":"Spyderco","offers":[{"title":"Default Title","offer_id":45332440252460,"sku":"MT21","price":69.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0562\/7189\/6620\/files\/8a3b3d33-29b7-435c-8685-9a299a3ecc02.jpg?v=1772148073","url":"https:\/\/spyderco.com\/products\/mule-team%e2%84%a2-cpm-4v","provider":"Spyderco","version":"1.0","type":"link"}
