The **Extrema Ratio Frame Rock** is a robust pocket knife based on the Ti-Rock, a knife made exclusively for one of the largest Italian distributors.

The Frame Rock is a heavy-duty pocket knife with a blade no less than 6 mm thick. The knife has a spearpoint blade with a DLC coating. You open the blade with the thumb rest, which moves very smoothly thanks to the ball bearings. A solid frame lock mechanism locks the blade when opened. There is also a hardened steel lockbar insert, so the locking mechanism is protected from wear and tear.

## Böhler N690 steel blade

The blade is made from Austrian Böhler N690 steel. This is a stainless steel with long sharpness retention that is also used for surgical tools. N690 is highly durable and can be sharpened until razor sharp.

## Titanium handle

The handle is made from anodized titanium. This is a premium, high-quality material. Titanium is also very lightweight and highly corrosion-resistant!

General information

We always measure the blade length ourselves. This is the length of the blade from the tip to the front of the handle. This may deviate from the manufacturer's specification.

Blade length

We always measure the blade thickness at the thickest part of the blade. Often just before the handle. This may deviate from the manufacturer's specification.

Blade thickness

We always weigh a product as bare as possible. Knives and axes always without their sheath, lights (if possible) without their battery. For knife sets we measure the entire weight. This may deviate from the manufacturer's specifications.
