Question:

whats the best steel to make a huge knife?

it has 2 be 20 inches overall, and 2and1/2 inches wide and .25 or more inches thick... im thinking truck steel but im not sure thx

Answer:

I made mine from a power hack saw blade. Granted it isn;t a quarter inch thick but it sure works well. Used the tooth part for the blade edge, just ground off the teeth. I can use a hammer or a stone on he back side of the blade to chop through the bone when cleaning deer.
What is the purpose of the knife? What properties do you want? Strength, flexibility, ability to hold an edge, ability to make razor sharp, ease to sharpen, resistance to corrosion, cost? What method are you going to use to make the blade? Cast, forge and hammer, multiple folds? Are you going to be a stabbing knife, a slicing knife, chopping knife, or just a pretty show knife? What is truck steel? Doesn't sound like it would be very good blade steel.
Well okorder /
A sawmill blade(circular type) It`s good steel already hardened and you saw out your knife pattern with a skill saw loaded with an abrasive cut-off wheel. Norton wheels are best from Home Depot.
