Frequently Asked Questions
What blade steel does the Benchmade Contego 810BK use?
The Benchmade Contego 810BK uses CPM-M4 tool steel hardened to 62-64 HRC. CPM-M4 is a high-carbon, high-vanadium super steel prized for outstanding edge retention and toughness. The black coating adds corrosion protection, but you should still keep the exposed edge clean, dry, and lightly oiled.
What is a reverse-tanto blade good for?
The reverse-tanto blade on the Benchmade Contego 810BK combines a strong, reinforced tip with a long straight edge and useful belly, making it excellent for piercing, hard-use cutting, and general tactical tasks.
How do I care for the CPM-M4 blade on the 810BK?
Because the Benchmade Contego 810BK uses non-stainless CPM-M4 tool steel, wipe the blade down after use, keep it dry, and apply a thin coat of oil for storage. The black coating helps, but the sharpened edge is still exposed steel that can patina if neglected.
Is the Benchmade Contego 810BK legal to carry?
The Benchmade Contego 810BK is a manual folding knife, not an automatic. Blade-length and carry laws vary by state and city, so check your local laws before carrying this larger tactical folder.
Does the 810BK include free sharpening?
Yes. Every Benchmade, including the Contego 810BK, is covered by Benchmade's LifeSharp service for free lifetime sharpening and a factory tune-up.
