Microtech Amphibian Ram-Lok S/E Outbreak Fluted Aluminum, Outbreak P/S M390MK by Tony Marfione (137RL-2FLOBS)

The Microtech Amphibian Ram-Lok 137RL-2FLOBS expands on the Amphibian design with a partially serrated edge, while retaining the milled aluminum handle and distinctive Outbreak finish. It is a large manual folder featuring Böhler M390MK steel, a RAM-LOK lock, and two types of cutting edges on a single blade.

The partially serrated edge expands its utility when working with ropes, straps, and fibrous materials, while still leaving a section of smooth edge for more controlled cutting. A thumb stud and ball bearings ensure smooth blade operation.

Böhler M390MK and a partially serrated edge

Böhler M390MK is a special variant of M390 developed for Microtech in collaboration with Böhler. This variant features a Part Serrated edge, which combines a smooth section of the blade with serrations useful for cutting more challenging materials.

Clip Point with a hollow grind

The Clip Point blade retains a precise tip and a long cutting edge. The hollow grind enhances aggressive cutting performance, and the decorative Outbreak finish gives the surface a unique character. The pattern placement may vary between individual knives.

Milled aluminum and robust RAM-LOK mechanism

The handle is made of milled aluminum, whose surface provides a distinct texture and complements the Outbreak’s irregular styling well. A full titanium backspacer secures the rear of the construction, and the titanium clip can be mounted on either side.

The blade is manually opened using a thumb stud. Ball bearings ensure smooth movement, while RAM-LOK locks the blade in the open position.

Technical Data

Frequently Asked Questions

How do I care for the M390MK?

After use, it’s a good idea to clean and dry the blade, especially after contact with moisture or substances that may leave residue. Periodic maintenance with a protective agent helps keep the surface in good condition.

How do I sharpen a partially serrated blade?

The smooth section of the edge can be sharpened using a standard sharpening method suitable for M390MK steel. The serrations require a narrower sharpening rod or another tool matched to their profile so as not to alter the factory-set geometry of the serrations.

What are the benefits of partial serrations?

The serrated section performs well with fibrous materials, ropes, and straps, while the smooth part of the edge remains useful for more precise, controlled cutting.

How does RAM-LOK work?

RAM-LOK locks the blade in place using a transverse component that slides within the handle. This design allows you to release the mechanism without placing your fingers directly in the path of the folding blade.

How do you clean the pivot mechanism?

It’s a good idea to periodically clean the area around the pivot and Ball bearings to remove dust and small debris. After cleaning, a small amount of a suitable lubricant is all that’s needed.
