• Happy Thanksgiving to all of you! I hope that you all have something to be grateful for this year and for many years to come
  • America has reached 250 years, and I am grateful to be here, in the best country in the world. Thank every one of you who helps make this country a better place, those who have gone before and risked it all, and those who've paid the ultimate price to make the United States what we are today.

    Happy Birthday America! Let Freedom Ring for all time!

I made up 10 plane blades for a woodworker last week out of A2, a lot of grinding because he wanted the tang fully tapered.

Now I know why so few makers use A2 on a regular basis. The darn stuff hardens right up if you get it too hot while grinding. Give me 440C anytime.

It did come back from heat treating with a great blue grey patina that could be an advantage if someone were to make tactical knives from it.
