Here's a new question on what is probably an old thread.

I've worked with D-2 before and find it somewhat slow to work, especially since I generally use O-1 carbon steel. On both I rough grind to about 75% of the final grind and then true up the surfaces and get the final finish after heat treat. That last 25% on D-2 is HARD. Nonetheless, I do like the performance of D-2. I don't get any warpage with the sizes I use.

How close to final grind can you get with D-2 b4 heat treat ?
Is there a risk of warpage if the sections are thinner ?
What have you guys found to be the "sweet spot" for hardness?
(I'm told its about 60-61HRC.)
Has anyone had problems with brittleness with D-2 given the high hardness counts ?
I know it makes an awesome cutting tool but what about toughness ?

A few questions there but I want to build a 6inch hidden tang drop-point hunter with 5/32inch stock D-2. It'll be a lot bigger than the 2-1/2inch blade neck knife I previously made. So before I invest time and money ...

Thanks and cheers.
