Product Description
The Benchmade Mini Infidel 3350BK brings the full-size Infidel's double-action OTF platform down to a 3.10-inch blade — the same D2 tool steel, same aluminum handle construction, and same deployment feel as the 3300BK, in a more concealable carry format for buyers who want the Infidel mechanism without the full-size footprint.
The blade is D2 tool steel with a black coating and double-edged flat-ground dagger profile. D2 delivers exceptional wear resistance and edge retention compared to fully stainless production steels, at the cost of requiring occasional oiling to prevent surface oxidation. The double-action OTF slider deploys and retracts the blade from the front of the handle with a single push in either direction — no separate retraction button. Black anodized 6061-T6 aluminum handle, machined to the same tolerances as the full-size 3300BK. At 2.68 oz the Mini Infidel carries noticeably lighter than the 3300BK while maintaining the same mechanism quality that defines the Infidel line.
