SOG PROHEN XR Folding Knife - Mikkel Willumsen Signature Edition (12-25-01-57)

The SOG PROHEN XR Folding Knife in the Mikkel Willumsen Signature Edition is a premium EDC blade built for hunters, field workers, and anyone who demands reliability in a compact package. Designed in collaboration with renowned knife maker Mikkel Willumsen, this folding knife combines refined ergonomics with proven S.O.G. engineering. The 3.35-inch drop point blade delivers versatility for camp tasks, processing game, and everyday cutting, while the black textured G10 handle provides secure grip in wet or gloved conditions.

The blade is forged from D2 steel treated with S.O.G.'s proprietary Cryo process—a cryogenic hardening technique that enhances edge retention and durability. The TiNi coating protects against corrosion and reduces glare, essential features for anyone operating in harsh environments. This is a serious cutting tool, not a showpiece: it's built to take real use and keep performing.

The drop point profile makes it equally at home in the field or on the bench. Whether you're skinning game, breaking down camp gear, or handling everyday carry tasks, the blade geometry gives you control without sacrificing reach. The textured G10 scales won't slip, even under demanding conditions or when your hands aren't dry.

Frequently Asked Questions

Is the SOG PROHEN XR a good hunting knife?

Yes. The 3.35-inch drop point blade is well-suited for field dressing, camp prep, and processing tasks. The D2 steel holds an edge through repeated use, and the Cryo treatment enhances durability under demanding conditions. The secure G10 handle works well in wet or cold environments.

What does the Cryo process do?

Cryogenic hardening is a heat-treatment process that enhances the steel's hardness and edge retention. S.O.G.'s Cryo treatment on D2 steel improves the blade's ability to maintain a sharp edge through extended use and makes it more resistant to damage.

Can I carry this knife every day?

Absolutely. The folding design and compact size make it suitable for everyday carry (EDC). The secure textured G10 handle and reliable blade make it practical for both routine tasks and unexpected field situations.

What is the TiNi coating?

TiNi is a protective coating that resists corrosion and reduces reflective glare. This coating helps the blade resist rust and oxidation while keeping the knife tactically discrete in the field.
