The **CRKT Seismic** is a large and solid pocket knife, designed by Flavio Ikoma. This is the first production pocket knife with Deadbolt lock. This is an incredibly strong mechanism, designed by Flavio Ikoma himself.

## Deadbolt lock

The most important part of the Deadbolt lock is the hardened steel wedge that falls into the cut-outs in the blade This construction is so strong it can handle quite a lot. Using it is easy: you simply press the large pivot to close the blade.

It is remarkable that you can adjust the so-called *detent* yourself. The show side contains a tiny torx screw, just before the middle of the handle. By turning it you can adjust how much pressure you need to take the knife from the handle. Some people feel a slight detent is great, others prefer a heavier one to make sure it doesn't open as quick. It is very unique you have this choice, especially on a knife in this price range.

You open the CRKT Seismic with the flipper or the double thumb stud. Because the blade is relatively large and runs on ball bearings it will open quickly. Flavio Ikoma is namely also one of the inventors of the IKBS ball bearing system. The blade is made from 1.4116. An originally German type of steel that is stainless and incredibly tough, but also easy to sharpen. The handle is made from G10. This version of the Seismic has a cool black coating on the blade.

This CRKT Seismic might be the first-ever pocket knife with Deadbolt lock, we don't expect it to be the last. Everyone needs to have tried such an amazing system at least once.

C'est le 1er couteau que j'achète et j'ai été très agréablement surpris en le deballant. On a une vrai sensation de robustesse, il a un très beau design et un tranchant redoutable, je ne regrette pas mon achat.

Een bijzonder mooi vormgegeven mes. Functioneel en vlijmscherp. Heb hem nu een paar maand en hij is nog steeds scherp

General information

We always measure the blade height at the highest part of the blade.

Blade height

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

value_blade_length_edge

The length of the cutting edge is measured from the tip to the start of the edge. This may deviate from the manufacturer's specification.

Cutting edge 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

value_closed_length

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.

Weight

Dimensions & weight

value_steel_hardness

The hardness in Rockwell C for a knife is always according to the manufacturer's specifications. When a manufacturer specifies a value of 56-58HRC, for instance, we always note the highest value, i.e. 58HRC.

Lock

We measure the sharpening angle ourselves. This value is the angle per side.  So 20º means that the total angle of the edge is 40º. Please note that knives are almost always sharpened by hand, even in factories. This value is therefore only an indication of a single tool measured by us. You are always free to choose your own sharpening angle. [Learn more about sharpening angles](/en/ct/sharpening-angles-explained.htm).

Sharpening angle

In terms of grind we are talking about how the complete blade thickness extends into the edge. Want to learn more about grinds? [Read all about grinds on knives](/en/ct/knife-grinds.htm).
