Duration: 14:40

This video tests the durability of various knives by striking their spines against shale rocks. The Buck Nighthawk (420 stainless) and the Ka-Bar/Ontario Rat 7 (1095 carbon steel) proved surprisingly tough. In contrast, a Bulgarian AK47 bayonet failed catastrophically, and a Cold Steel Chaos experienced handle failure, highlighting design weaknesses despite blade integrity. The test emphasizes the importance of steel type and heat treatment for durability.

Quick Summary

The 'Knife Graveyard' test involves striking knife spines against shale rocks to check for brittleness. The Buck Nighthawk and 1095 carbon steel knives like the Ka-Bar and Ontario RAT 7 proved durable, while a Bulgarian AK47 bayonet snapped and a Cold Steel Chaos handle broke.

Frequently Asked Questions

What is the 'Knife Graveyard' test?

The 'Knife Graveyard' test, as demonstrated by Nutnfancy, involves striking the spines of various knives against hard shale rocks. This method aims to assess the blade's brittleness and overall structural integrity under extreme stress, revealing potential weak points in design and materials.

Which knives performed well in the rock strike durability test?

The Buck Nighthawk (420 stainless) and the Ka-Bar Utility and Ontario RAT 7 (both 1095 carbon steel) performed exceptionally well, surviving numerous hard strikes without significant structural damage, showcasing their toughness and resilience.

Did any knives fail during the rock strike test?

Yes, a Bulgarian Circle 10 AK47 bayonet catastrophically failed, snapping in half after only a few strikes. Additionally, the cast metal handle of the Cold Steel Chaos broke, despite the blade remaining intact.

What does the test reveal about different steel types?

The test highlights the durability of well-tempered 1095 carbon steel (Ka-Bar, RAT 7) and the surprising toughness of affordable 420 stainless steel (Buck Nighthawk). It also shows that some premium steels (Cold Steel San Mai III) can perform well, while others (Bulgarian bayonet steel) can be extremely brittle.
