Custom s90v chef knife.

Progression of the blade and the carbon and gold handle material.
Hope gave dies mind but it liking the way it's coming together.
When I get her I'll do some onion cutting. Lol

Any thoughts on the heat-treat and hardness? I think in the k-tip chef knife 59 might be ideal. Any thoughts?

Are you saying you're contemplating getting an S90V blade at 59HRC?

I'm thinking from what I'm told the 59 is very balanced in retention and toughness.
That's the shape before heat treat.

I’d go higher to take more advantage, S90V is not tough but not super crisp neither, it can take some beat

I’d go harder, say 63. Unless you’re breaking through turkey spines that should leave some toughness while showing that steel’s finer qualities.

What do you suggest and do you have the heat treat guidelines?

He was following the recommended heat treat. Naturally.

[jedy617]

Ah yes the recommended one. I like that one

 

[insidiousaudio]

Naturally.

Yea I mean crucible recommends of 59. I was shooting for a 61.

 

[insidiousaudio]

Ah yes the recommended one. I like that one

I can see how custom heat treat makes a difference but honestly going against a manufacturer's recommendations can be tricky. I know from my line of work then again I know with a lot of exp you find the ideal parameters for the desired outcome. Reguardless

Latin wrote quite a bit about S90V,@MSicardCutlery did some all the way up to 63-64, Spyderco ones are usually 60-61

It's crazy it's almost like he didn't watch that geometry being the biggest influence for edge retention, and is now gonna have a soft thick s90v axe probably lol. I'm sure it will be great going through pigs like in forged and fire

59 is for spatulas - don’t be a coward

The blade measures 1.8 mm at the thickest spine 8.4 long with a lazer grind. Not much behind the edge so that's where I'm concerned about a high HRC.

Yea I don't want It to be chippy. But I'm thinking 61 is a good medium
