In the Amphibian Ram-Lok model, this material performs well when cutting tape, cardboard, cord, straps, plastics, and technical materials, where stable edge performance and predictable blade guidance are essential. The Stonewashed finish gives the blade a practical, satin-matte character and helps mask minor marks that arise during regular use.

S/E Drop Point and flat grind – functional geometry with a strong tip

The S/E Drop Point profile combines a durable tip with a functional edge line, making it well-suited for tasks requiring control, cutting, and precise scoring. The flat grind facilitates smooth blade glide through material while maintaining an optimal balance between cutting efficiency and structural strength. The wide Amphibian blade gives the knife a distinctive, tactical-utility character, and the jimped thumb guard jimping improves control during heavy-duty work.

Ram-Lok and ball bearings – smoothness, safety, and two-handed operation

The opening mechanism is based on ball bearings, which support smooth, responsive blade operation using a strong on both sides . The Ram-Lok lock uses a crossbar that moves within the handle guides, stabilizing the blade when open and allowing for comfortable release of the lock with either the right or left hand.

Slab Side Titanium and Flamed HW – Marfione Select titanium construction

Frequently Asked Questions

How do I care for and sharpen the Böhler M390MK steel in the Amphibian Ram-Lok model?

Böhler M390MK steel should be cleaned and dried after use, especially after contact with moisture, sweat, or debris from cut materials. A diamond sharpener or a high-quality ceramic system works best for sharpening, as powder steel with high wear resistance requires an effective abrasive and a stable angle guide.

How does the Ram-Lok lock work?

Ram-Lok uses a crossbar that, when opened, engages the rear of the blade and stabilizes the blade in the working position. The lock is released by pulling the bar, accessible from both sides of the handle, which facilitates operation with either the right or left hand.

What makes the S/E Drop Point profile stand out?

The S/E Drop Point provides a strong tip, good blade control, and a versatile edge line. This geometry works well for cutting cardboard, tape, cord, plastics, and other technical materials.

What are the benefits of the Slab Side Titanium handle?

The Slab Side Titanium handle combines high rigidity, durability, and a collector’s-grade appearance. The flat surfaces of the titanium liners highlight the precision of the craftsmanship, and the Flamed HW hardware sets the Marfione Select variant apart from standard Amphibian versions.

Is the Microtech Amphibian Ram-Lok comfortable for left-handed users?

Yes, the Ram-Lok lock, the dual thumb stud, and the right/left tip-up clip make it easy to use for both right- and left-handed people. This is one of the practical advantages of this design.
