Benchmade Auto Immunity 2.5in Automatic Folding Knife Wharncliffe Blade Charcoal Grey Handle. 5" in most federal buildings. Many jurisdictions have blade length restrictions on both manual and auto folders. Anyone looking for a small easy-to-conceal folder or auto that is effective for both daily utility and as a backup-edged weapon in non-permissive environments needs to look no further. The clipped Wharncliffe blade style coupled with the CPM-M4 boasts outstanding edge retention. The steel supports the ultra-fine point of the blade. This is effective as both a utility blade and for self-defense as it focuses all of the knife's cutting force on the needle-thin tip. The included lanyard extends the handle giving this small knife a full grip that is easy to access. The Immunity was conceived designed and developed entirely during the pandemic-hence the name.
