Benchmade Auto Presidio II 5700SGY-1 – CPM-M4 Automatic Knife
The Benchmade Auto Presidio II 5700SGY-1 is a discontinued, collector-grade configuration of Benchmade's proven out-the-side (OTS) automatic knife. It pairs a 3.72" grey-coated CPM-M4 drop-point blade with a serrated (combo) edge and a milled burnt bronze aluminum handle, fired by the fast, fully ambidextrous Auto-AXIS mechanism. For anyone searching for a premium American-made automatic knife — often called a switchblade — with true hard-use tool steel, this is one of the strongest configurations Benchmade ever shipped.
Designed and manufactured in the USA at Benchmade's Oregon City, Oregon factory, the Auto Presidio II 5700SGY-1 delivers outstanding edge retention and toughness from CPM-M4 (62–64 HRC), while the grey blade coating and Cerakote-finished handle add wear and corrosion resistance for EDC, duty, and tactical carry.

Frequently Asked Questions
How does the Benchmade Auto Presidio II 5700SGY-1 open?
The Benchmade Auto Presidio II 5700SGY-1 uses Benchmade's Auto-AXIS mechanism: slide the ambidextrous AXIS toggle and the CPM-M4 blade fires open from the side and locks solidly; the same toggle releases it for safe one-hand closing.
Are automatic knives like the Benchmade Auto Presidio II 5700SGY-1 legal?
Automatic (switchblade) knife laws vary by state, and some states restrict blade length or require civilian, military, or law-enforcement status. Before buying the Benchmade Auto Presidio II 5700SGY-1, check your state and local laws to confirm automatic knives are legal to own and carry where you live.
What steel does the Benchmade Auto Presidio II 5700SGY-1 use?
The Benchmade Auto Presidio II 5700SGY-1 uses CPM-M4 tool steel hardened to 62–64 HRC, prized for exceptional edge retention and toughness. CPM-M4 is not stainless, so keep the Benchmade Auto Presidio II 5700SGY-1 clean and lightly oiled; the grey coating protects most of the blade.
How is the Benchmade Auto Presidio II 5700SGY-1 different from the 5700 and 5700SBK?
The Benchmade Auto Presidio II 5700SGY-1 is the upgraded CPM-M4 version: the standard 5700 and black 5700SBK use CPM-S30V stainless steel with plain edges, while the 5700SGY-1 runs harder CPM-M4 (62–64 HRC) with a serrated combo edge, grey blade coating, and burnt bronze handle.
