What Is THE TOUGHEST KNIFE STEEL? Testing knife steel.

What is the toughest knife steel for the ultimate knife? Today was test some super tough knife making steel, S7 and 1084.

This is not a super scientific test, but I think it goest to show just how tough these steels are.
--------------------------------------------------------------------------------------------------------------
Heat treatment for s7:

Hardening Crucible Recommended

Preheat: 1350/1400F, equalize.

High Heat: 1725/1750F, hold 30/45 minutes at temperature.

I heated to 1725F wrapped in foil and held for 40 minutes.

Quench: Air, positive pressure vacuum, interrupted oil to 150F. Sections over about 3" thick may require oil quenching to attain full hardness.

I quenched in air.

Temper: 350/1000F, hold one hour per inch of thickness (two hours minimum), air cool to room temperature. Double tempering is recommended.

I tempered at 400 for 2, two hour cycles.

Heat treatment for 1084
Normalized 1600f / 1425F / 1200F
cool in still air

Heated to 1475 hold 5 minutes quench in parks 50

Temper at 440F 2x2hr

Do you think the mora basic would hold up to the same abuse? Or does it even matter 🤷‍♂️

[chrisgrisham]

The whole point was a knife he wanted folks. 1) lightweight, 2) durable, 3) full tang tough that could hold an good edge.

I don’t think there is a knife on the market that could handle the abuse I just witnessed! I was astounded! First, who would treat a knife like this?😂😂

Your test was a success and I’ll be the first in line to order one of those knives in what ever steel you choose to make them out of.

Awesome job and you get a star for courage on this...😂😂

I always say this, but I'll say it again. Your production is just top tier man. Definitely S class. SSGSS. Ultra instinct editing.

Absolutely stunned by your vid. Last year I destroyed a blade made by me in 2006 from 1045 by batoning and the tang was only 4, 5 mm width. I always think how our ancestors had to use their blades in daily use and always come to the conclusion there is always a way to breake your knive missusing it. It is a knive not a tank or an axe and also it is always incredible what the steel is capable of. Thanks for your effort showing that ability to us.

Hi. When both blades broke i noticed the bolts were not tight and were moving. If they were tight would the metal still have broken? Good health and stay safe.

[debbiebissel]

One thing that the test showed me was that you are one he'll of a knife maker, I enjoy all of your videos and I'm learning a good bit to improve my skills.Thank You Jake Bissel.

[jeremybake]

Exactly the video I was looking for. It makes me feel even better about the 1084 I have. Thank you.

When you cut out the handle opening you may want to put a generous radius/chamfer on the edges of the opening, because that will be the #1 failure area (stress risers). AFAICT from video, that wasn't done. Indeed the failure in both cases was in the cut out handle area. Sharp corners will always lead to failure. (From what I've seen, most manufacturers "cheap out" on anything hidden by handle scales and don't properly radius their cut-out edges. Saves them a few bucks in costs...)

s7 is used on high end ar15 bolt carrier groups. super cool to see it in action in a different application.

[RAkers-tuey]

Try gun bluing (hot blue) on the S 7.
Looks cool, and stops rust.

I think we learned we should have more protective gear on when testing knife destruction!!! 😂😂😂

[netheonly]

Hey, do you sell your work, I would love a blade in s7 with a full tang handle. Let me know if you could do that please?

[Thepreppersbunkeroutdoors]

I wish more people tested like this!!! The only think i would like to add is to get more hp on the blade a much heavier baton goes a long way. I prefer a hunk of wood at least 5" in diameter at least 12" in length at full width with a nice handle. Keep up the hard work!

[jamesd]

I was a Tool and Die maker and often wondered why didn't make Knives Out of S7 shock resistant tool steel perfect👍👍

[jamesnelson]

Impressive! This test needs to be seen by all the people that criticize batoning with a knife

[markfulmer]

Another great video! I was really surprised by the 1084!

[STruple]

You always upload right when I'm deciding if I'll go to sleep or .. oh look, new outdoors55 video!

[noname-zpzk]

im absolutely loving this series. Id love to buy a knife when its done!

[e.t.preppin]

Wibble bobble. That’s it you are my hero knife maker beater upper with words like wibble bobble. I’m super impressed and as always very entertained!!!!

[drunkenblacklocustbushcraf]

I'd be interested seeing how the tool steels like O-1, A-2, and L-6 preform. I understand L6 is considered to be really good survival knife steel. I've never used it to know.
