This model was launched by Extrema Ratio to fill a niche. Customers have been asking for a utility folder of this type - one that goes beyond being just a “pocket knife”.

The M1A1 is a useful basic folder plus much more. Definitely an EDC that will ride comfortably in your pocket or you can use the bridge clip to anchor it. The M1A1 is probably better described as a “tool” rather than a “knife”.

This tool contains the essential utility blade with a drop point, a handy can opener, a cap lifter with a screwdriver, and a marlin spike which is a useful tool for any type of rope work. This model comes with a black handle and stone washed blade/tools/clip.

If you are a fisherman, or a rock climber, or enjoy recreational boating, or go camping/hunting, or need a useful tool to add to your survival gear, or have a bug-out bag - the M1A1 is the handy tool for you.

If you have a Boy Scout in your family, this would make a great gift for him. The M1A1 has the tools a Scout needs.

The M1A1 is rugged. Multi-functional. Embedded with the quality and styling that are characteristic of Extrema Ratio.
